Crosstalk Improvement of Polymer in Glass Thermo-Optical Multimode Interference Switch
Abstract: A new structural design
of combined variable optical attenuator (VOA) and optical switch has been
proposed in this paper. The design is based on the multimode interference (MMI)
architecture and it has been demonstrated for crosstalk improvement of optical
switch. The device operates by manipulating thermo-optic (TO) effect that
naturally existed in all optical waveguide material. By applying a polymer on
glass material platform, the optimized VOA with optical attenuation of 21.52 dB
has been achieved with applied power of 36.4 mW. The simulation result shows
that the VOA helps to achieve significant improvements of optical switch
performance particularly in crosstalk reduction up to 89.66%.
