We designed and evaluated 1×2 and 2×2 optical couplers using multimode interference (MMI) optical waveguides of Ti-diffused LiNbO3. A Mach-Zehnder electrooptic modulator (MZM) designed using those two MMI couplers as an optical power splitter and ...

Optical couplers based on Multi-mode interference (MMI) were considered using Ti-diffused LiNbO3 (Ti:LN) waveguides. Properties of MMI waveguides of Ti:LN were analyzed using the beam propagation method. An optical 90-degree hybrid of the MMI stru...
