Silicon photonics adds optical functionality to electronic integrated circuits allowing leveraging
CMOS fabrication processes, integration of
CMOS electronics discretely and integration of
microelectromechanical systems (MEMS) or Micro-Opto-Electro-Mechanical-Systems (MOEMS) elements. Further,
silicon photonics allows
hybrid or monolithic integration of
semiconductor photodetectors for
optical receivers in conjunction with the passive
silicon photonics and active elements such as
semiconductor optical amplifiers (SOAs) and
laser diodes (LDs) for coherent detection receivers for next generation systems. Accordingly, it would be beneficial to provide network designers with
silicon photonic receivers for
wavelength division multiplexed networks using direct or coherent detection which can dynamically select one or more channels from a large number of incoming channels whilst addressing the inherent issues that
silicon photonics and other optical
waveguide technologies exhibit such as polarisation dependency.
