Diffractive Optical Network Supports Quantitative Phase Imaging
A team of researchers led by Aydogan Ozcan from the Electrical and Computer Engineering Department and California Nanosystems Institute at UCLA has developed a diffractive optical network to replace digital image reconstruction algorithms used in quantitative phase imaging (QPI) systems. The technology uses a series of passive optical surfaces that were spatially engineered with deep learning.

Unlike conventional QPI systems, where phase recovery is performed on a computer using an intensity measurement or a hologram, a diffractive QPI network directly processes the optical waves generated by the object itself to retrieve the phase information of the specimen as the light propagates through the diffractive network. The entire phase...]]>

Topological Cavity Widens Functionality of Surface-Emitting Lasers
Researchers at the Institute of Physics of the Chinese Academy of Sciences have incorporated a topological cavity into the design of a surface-emitting laser to create a device that addresses the challenge of simultaneously increasing output power and beam quality in semiconductor lasers — a principal bottleneck. The research team’s topological-cavity surface-emitting laser (TCSEL) achieved 10 W of peak power, subdegree beam divergence, a 60-dB side-mode suppression ratio, and 2D multiwavelength array lasing at 1550 nm — which is considered crucial for communication and is also an eye-safe wavelength.

The TCSEL was also demonstrated to operate at any other wavelength range. The laser’s specifications and...]]>

Modular Waveguide Represents Step Toward Faster Quantum Computers
Researchers at the University of Tokyo generated strongly nonclassical light using a modular waveguide-based light source. The demonstration, which the researchers said is the first of its kind, is poised to benefit future work aimed at creating faster and more practical optical quantum computers.

Continuous-wave squeezed light is used to generate the various quantum states necessary to perform quantum computing. For optimal computing performance, the squeezed light source must exhibit very low levels of light loss and be broadband.

In the work, the researchers generated a state of light known as Schrödinger or Schrödinger’s cat, which is a superposition of coherent states. The team created a waveguide optical...]]>

Tunable Nanophotonic Interface Simplifies PIC Integration
A chiral nanophotonic interface developed by a research team at the University of Chicago could make photonic integrated circuits (PICs) easier to integrate into mapping systems, biosensors, and other technologies. The interface provides a way for PICs to direct light at the nanoscale.

PICs typically use optical isolators to control the direction of light. These devices prevent light from reentering and destabilizing a system, but they often require large components that make it challenging to create small-scale PICs.

The researchers fabricated titanium dioxide (TiO2) waveguides directly onto the surface of boron nitride (BN)-encapsulated tungsten diselenide (WSe2), integrating light confined in a nanophotonic waveguide with...]]>

Metal-Wire Waveguides Deliver Unparalleled Terahertz Network Efficiency
A research group at Institut national de la recherche scientifique (INRS) in Quebec has achieved broadband terahertz (THz) signal processing by directly engineering the wire surfaces of metal-wire waveguides. The approach allowed multiscale-structured Bragg gratings to be directly etched on metal wires without the need to introduce additional materials.

When paired with diverse waveguide designs, the INRS team’s approach could provide a structurally simple platform for achieving exceptional signal processing capabilities in the THz regime.

This is the first time such an approach has been applied to THz frequencies, the researchers reported. The team was led by Roberto Morandotti.

“By engraving judiciously...]]>

Fusion Splicing Achieves Low Loss in Spacing-Mismatched Multicore Fibers
Researchers at Fudan University demonstrated low-loss fusion splicing techniques between spacing-mismatched multicore fibers (MCFs). According to the researchers, the work builds on previous studies — including from other research groups — that addressed the challenge of multicore splicing but did not address MCF splicing with any mismatched spacings.

Multicore fibers offer numerous advantages over single-core design, in transmission capacity, space saving integration, and the ability to eliminate cross-sensitivity. By these merits, the technology demonstrates a range of potential applications, but it is hindered by a lack of manufacturing standards.

“For dissimilar MCFs with different core-to-core spacings,...]]>

Data Hacks Demonstrate IT Networks’ Need for Optical Protections
Information technology computer scientists at Karlsruhe Institute of Technology (KIT) have demonstrated how data can be transmitted to LEDs — contained in regular office devices such as a printer — using a directed laser. The demonstration shows the ability for data hackers to secretly communicate with “air-gapped” computer systems over distances of several meters.

According to the team, this shows that in addition to conventional information and communication technology security, critical IT systems must also be protected optically.

The collaborative work with researchers from KIT, TU Braunschweig, and TU Berlin was presented this month as the LaserShark attack at the 37th Annual Computer Security...]]>

Biosensor Barcodes Track Cancer Cell Communications
Johns Hopkins University researchers have developed a method for identifying and tracking cells in a manner similar to the way barcodes are used to identify and track products. The team used the method to study the way that cancer cells “talk” with one another.

“When cancer cells communicate, numerous proteins constantly change how they interact with one another,” said senior author Chuan-Hsiang (Bear) Huang, assistant professor of pathology at the Johns Hopkins University School of Medicine. “Studying this signaling in depth and in real time has traditionally been difficult, so we needed a method that could simultaneously image, track, and analyze everything happening in the network, and therefore,...]]>

Simpler Approach Produces Highly Chirped Laser Pulses
Researchers at the University of Rochester’s Institute of Optics have produced ultrashort, extremely high-energy (chirped) laser pulses using a spectral filter in a Kerr resonator. Kerr resonators, which operate without amplification, are of interest to researchers globally due to their ability to support behaviors that include broadband bursts of light. The pulses created in the work remained stable in low quality-factor resonators, despite large dissipation.

The demonstration used relatively low-quality and inexpensive equipment, the researchers reported. By adding a spectral filter in a Kerr resonator, a type of optical cavity, they were able to manipulate a laser pulse in the resonator to widen its wavefront by separating...]]>

4-channel Silicon Multiplexer to Advance Terahertz-Based Communications
An ultra-small silicon chip called a multiplexer is poised to increase data processing speeds and the next generation of communications — 6G and beyond — as a result. The chip, developed by researchers from Osaka University and the University of Adelaide, is made from pure silicon and manages terahertz waves in the 300 GHz band.

According to associate professor Withawat Withayachumnankul from the University of Adelaide, a multiplexer, which is used to split and join signals, is critical for dividing information into manageable chunks that can be more easily processed to speed up transmission from one device to another.

“Up until now, compact and practical multiplexers have not been developed for the terahertz...]]>

3 Questions with Tom Hausken
With COVID-19 affecting the nation’s economy in every sector, photonics industries have been working to respond to closing factories and delayed exports. Tom Hausken, OSA’s senior industry adviser, offered Photonics Media a look at the current state of the industry.

Photonics Media: What impact have you seen on sectors of the photonics industry as a result of COVID-19?

Tom Hausken: The immediate effect is that the supply chains are disrupted. They were already changing before with the trade war, and now very much more so. But it’s not easy to change suppliers. If you can find new suppliers and qualify them, you may not be able to get the parts on planes right now. And if you can,...]]>
