| Abstract: | We present a current controlled passive 1×8 InP/InGaAsP optical matrix switch for routing applications at wavelength 1.55 μm. It is realized in a tree architecture and has integrated tapers for efficient fiber butt coupling. An AR coated device has average fiber-chip-fiber insertion losses of 6.8 and 6.3 dB for TE and TM polarizations, respectively. The homogeneity of the eight outputs is better than 0.3 dB in each polarization state. The crosstalk suppression is better than 19 dB. The performance of the device indicates that large InP-based switching matrices can be realized |
