Resumen
Compact low-loss polarization independent vertical coupling
between a 1.55 μm InGaAsP bulk active waveguide and a passive
waveguide based on bimodal interference is presented. Simulation results
show low coupling loss (<0.1 dB) over coupler lengths more than 5 times
shorter than using the adiabatic design. The concept avoids submicron
photolithographic features and shows acceptable fabrication to ...
