We present a novel photon-acid diffusion method to integrate polymer microlenses (MLs) on
a four-channel, high-speed photo-receiver consisting of normal-incidence germanium (Ge) …

In this paper, the frequency responses of InP/InGaAs vertical-incidence pin photodiodes with
various optical apertures of 50–80 μm are investigated. The same resonant frequency (f R) …

A monolithically integrable pin waveguide photodiode (WGPD) has been theoretically
analyzed and experimentally demonstrated. The pin WGPD comprises of a single quantum …

Hybrid integrated photonic circuit technology realizing high bandwidth coherent receivers is
presented. Integrated coherent receivers based on chip-to-chip coupling between high …

A parallel array of 10 side-illuminated waveguide photodetectors (WGPDs) with double-
cladding structure was designed and fabricated. In order to achieve high coupling efficiency …

We present a cost-effective and bandwidth-enhanced 64-Gbaud micro-intradyne coherent
receiver based on hybrid integration of InP waveguide-photodetector (WG-PD) and silica …

This article presents an optimization of waveguide photodiodes based on evanescent
coupling, adiabatic coupling and resonant coupling to achieve high optical coupling …

We present optimized structure of waveguide photodetector (WGPD) having large
responsivity in spite that its absorption layer is thin. Through beam-propagation method …
