We demonstrate a 140G/70G PON with over 37-dB optical power budget and 40-km reach employing phase retrieval direct detection receivers which are low-cost and colorless ensuring compatibility with

We report the experimental implementation of a wireless transmission system with a 146-GHz carrier frequency which is generated by optical heterodyning the two modes from a monolithically integrate

We present a barrier, reservoir and quantum well electron transfer intensity modulator at 1.55 micron with the largest electrical bandwidth reported to date, 15 GHz.

Quantum Well Infrared Photodetector (QWIP) usually suffer from a too moderate quantum efficiency and too large dark current which is often announced as crippling for low flux applications.

A monolithic extended-cavity semiconductor laser with an integrated Bragg reflector is used as a soliton source for a recirculating fiber loop with 980-nm diode-pumped Erbium doped fiber amplifiers

We demonstrated a 15-spatial-mode photonic lantern fabricated with the ultrafast laser inscription technique. The fabricated device showed

We have developed 920-nm pump modules for Yb-doped fiber amplifiers. The pump laser utilizes a single layer of In(AlGa)As/GaAs quantum-dot material as active region.

First long haul full C-band 32Gbaud PDM 16-QAM transmission experiment is demonstrated.

Optical pulse propagation over more than 15000 km was achieved using a reentrant 75 km fiber loop and a non-generative repeater to balance the optical losses.

We demonstrate a record distance with N * 43 Gb/s RZ-DQPSK modulated channels.
