We present a silicon photonics coherent optical subassembly, which has electro-optic/ optic-electro bandwidths of 54 GHz/52 GHz for a transmitter/receiver. We also demonstrate up to 96 Gbaud polarization multiplexed 16QAM signal generation and detect

As optical networks have evolved from point-to-point systems to ring or mesh networks, the optical devices that are needed to construct optical nodes have become more important and need to be more scalable. Hybridization of waveguide and free-space o

We propose a compact transponder aggregator (TPA) consisting of a wavelength selective switch (WSS) array and a direction switch array. It has no intrinsic splitting loss and therefore the number of ports can exceed that of a conventional multicast s

A wavelength selective switch (WSS) is proposed based on a Bragg reflector waveguide array, which has a footprint of only 2 × 6 mm2. We demonstrated arbitrary switching among 182 output ports by using a liquid crystal on silicon as a switching engin

We propose a waveguide frontend with integrated polarization diversity optics for a wavelength selective switch (WSS) array with a liquid crystal on silicon switching engine to simplify the free space optics configuration and the alignment process in

A compact integrated 1×2 wavelength-selective switch (WSS) is demonstrated for which the structure is designed such that the WSS has no waveguide crossings. By employing a loopback configuration, only one arrayed-waveguide grating is needed in the W

We describe an optics system that takes advantage of free space optics and waveguide optics. It offers attractive features for ROADM devices such as optical filters, tunable optical impairment compensators, and wavelength selective switches.

A tunable optical dispersion compensator that uses cascaded arrayed-waveguide gratings and an integrated phase shifter is reported. It is a catoptric circuit but does not require a circulator. The dispersion is successfully controlled from +142 to +1
