title: InP monolithically integrated wavelength selector based on periodic optical filter and optical switch chain.
abstract: We present an InP monolithically integrated wavelength selector that implements a binary search for selecting N modulated wavelengths. The wavelength selector filter is realized using log(2)N an active Mach-Zehnder interferometer filter and broadband optical gating elements. Nanosecond reconfigurable operation with a spectral-alignment over 3.2 nm free spectral range is achieved with an extinction ratio exceeding 25 dB. Error-free operation of the wavelength selector for four modulated wavelengths with 2 dB of power penalty is demonstrated.
