We present a 0.4-mm-large high-speed photodetector (PD), formed by series and parallel connected integration of 40 m diameter PDs. We successfully achieved the same 3-dB bandwidth (8.5 GHz) as that in 40 m single PD.

Optical couplers based on Multi-mode interference (MMI) were considered using Ti-diffused LiNbO 3 (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 struct
