Scalable InP integrated wavelength selector based on binary search

Opt Lett. 2011 Oct 1;36(19):3846-8. doi: 10.1364/OL.36.003846.

Abstract

We present an InP monolithically integrated wavelength selector that implements a binary search for selecting one from N modulated wavelengths. The InP chip requires only log(2)N optical filters and log(2)N optical switches. Experimental results show nanosecond reconfiguration and error-free wavelength selection of four modulated wavelengths with 2 dB of power penalty.
