Abstract :
An optical hybrid design based on paired multimode interference couplers in silicon-on-insulator process is investigated. The device exhibits greater than 20 dB CMRR and low phase deviation (<;10°) over 30 nm in the C-band. The design eliminates the use of optical cross waveguides for integration with balanced photodetectors.
