Wavelength control and monitor for dense wavelength division multiplexing (DWDM) silicon photonic receiver
Abstract
Techniques and circuitry for wavelength monitor and control are disclosed herein. The disclosed wavelength monitor and control circuitry and techniques are designed to realize a multi-channel DWDM optical link by using a photonic receiver that dynamically adjusts resonant wavelengths of the microring drop filter (MDF), as needed. The wavelength monitor and control circuitry can monitor and control the resonant wavelengths of multiple MDFs for a DWDM silicon photonics receiver with minimum power and area overhead. In an embodiment, circuitry for an optical receiver comprises an MDF having resonant wavelength for multiple DWDM channels, and circuitry to control and monitor the resonant wavelength of the MDF in real-time and in manner that compensates for deviation between actual resonant wavelength of the MDF and the incident optical wavelength of the MDF.
