Not Accessible

Your library or personal account may give you access

Abstract

A four channel Multi-Grating Filter (at 1.55 microns) with polarization-independent channel positions and two integrated amplifiers has been fabricated in InGaAsP/InP. A packaged device has no fiber-to-fiber loss and worst case crosstalk below -18 dB.
