They also can act as an electrical...Photonics HandbookPolarization Mode Dispersion: Concepts and Measurement: The performance of high-speed, digital fiber optic communications systems depends upon how reliably the receiver is able to distinguish closely spaced bits of information. Dispersive effects — physical mechanisms that broaden transmitted pulses — degrade this process.There are three fundamentally different dispersive phenomena in optical fiber, of which polarization mode dispersion (PMD) is the most complex. In digital multimode fiber systems, a light pulse...Photonics HandbookPhotonic Component Manufacturing: Moving Toward Automation: A shift in assembly methods would help reduce costs and increase production in the optoelectronics manufacturing and packaging industries.Manufacturing the laser diode is complicated by the existence of multiple proprietary techniques and intellectual property barriers together with complex device physics and unique materials. ...Photonics HandbookSemiconductor Lasers: An Overview of Commercial Devices: Within only a few decades, the semiconductor laser diode has evolved into a family of robust, reliable devices, with individual conversion efficiencies of better than 60 percent, continuous output powers of several kilowatts, modulation rates of several tens of gigahertz, and wavelengths from 0.4 to beyond 2 µm.
