ENGLEWOOD, Colo., May 23, 2024 — Optical communications technology company Lightwave Logic has launched a collaboration with Advanced Micro Foundry (AMF) to develop polymer slot modulators utilizing AMF's silicon photonics platform. The agreement comes amid an ongoing collaboration over the past year in which the companies have teamed to develop electro-optic polymer slot modulators using AMF's standard manufacturing process flow on 200-mm wafers.

As part of the optical transmit engine inside a pluggable optical transceiver, optical modulators use fiber optic cables to modulate laser light used for data transmission. Conventional optical modulators are semiconductor-based, and comprised of lithium niobate, indium phosphide, and silicon. Polymer slot modulators have been shown to achieve voltage below 1 V and data rates of 200 Gbps pulse amplitude modulation level 4 (PAM4). The performance is suitable for use with 800 Gbps and 1.6 Tbps pluggable transceivers for optical connectivity for large generative AI computing clusters.

“Electro-optic polymers offer a way to turbo-boost silicon photonics, as the performance of silicon photonics has hit a wall,” said Michael Lebby, CEO of Lightwave Logic. The companies now plan to further develop the modulators to ensure accessibility for product companies on a manufacturing scale.

In the context of electronics and semiconductor manufacturing, a wafer refers to a thin, flat disk or substrate made of a semiconducting material, usually crystalline silicon. Wafers serve as the foundation for the fabrication of integrated circuits (ICs), microelectromechanical systems (MEMS), and other microdevices. Here are key points regarding wafers: Material: Silicon is the most commonly used material for wafer fabrication due to its excellent semiconductor properties, high purity,...
A semiconductor is a type of material that has electrical conductivity between that of a conductor and an insulator. In other words, semiconductors have properties that are intermediate between metals (good conductors of electricity) and insulators (poor conductors of electricity). The conductivity of a semiconductor can be controlled and modified by factors such as temperature, impurities, or an applied electric field. The most common semiconductors are crystalline solids, and they are...
Polymers are large molecules composed of repeating structural units called monomers. These monomers are chemically bonded together to form long chains or networks, creating a macromolecular structure. The process of linking monomers together is known as polymerization. Polymers can be classified into several categories based on their structure, properties, and mode of synthesis. Some common types of polymers include: Synthetic polymers: These are human-made polymers produced through...
