Thermo-optical compensation in high-index contrast waveguide system (a-Si on SiO2) is reported using different cladding materials. We experimentally demonstrate the thermo-optically compensated a-Si based racetrack ring resonators with an acrylate po

We present the design and fabrication of temperature-insensitive high-index-contrast waveguides using acrylate polymer claddings. The large negative thermo-optic coefficient of the polymers effectively compensates the intrinsic positive thermo-optic

We propose a 40-channel ROADM subsystem based on polymer and silica planar lightwave circuits. It exhibits ultra-low power consumption and compact size, while meeting the requirements for high optical performance, high reliability, and low cost.

We review the main ROADM subsystem technologies, and propose a 40-channel PLC-based ROADM subsystem that exhibits ultra-low power consumption and compact size, while meeting the requirements for high optical performance, high reliability, and low cos

Summary form only given. Until recently, reconfigurable optical add/drop multiplexer (ROADM) systems did not exist, their components were unselected, and their market was unclear. Today every major system vendor has a ROADM offering, and a large numb

We present experimental results on the first integrated optical 16/spl times/16 strictly non-blocking polymeric switch matrix based on 1/spl times/2 digital optical switches. The prototype exhibits an insertion loss around 6 dB and an extinction of b

Electrical interconnects are reaching their fundamental limits and are becoming the speed bottleneck in data communications. Polymer waveguides with propagation losses below 0.01 dB/cm at 800-900 nm are available, and are enabling practical optical c

We describe a 4-channel metro ring node module that performs add/drop, protection switching, and power equalization functionalities on a single chip. The worst-case insertion loss is 1.25 dB.

The integration of magneto-optical devices enables cost and size reduction in optical commutication systems. Nonreciprocal phase shifters can be used to build polarization independent isolators and circulators. New photonic bandgap materials with hig

We present experimental results on an ultra-low drive power 8-channel variable optical attenuator array realized in a highly-integrated planar waveguide platform. The variable optical attenuator (VOA) array features an attenuation range of >25 dB wit
