We present the principle, implementation, and performance of a recently introduced high-sensitivity modulation format based on the combined use of polarization-division-multi-plexed quadrature phas

We propose a power-efficient modulation/detection scheme that combines PDM-QPSK and 16-ary-pulse-position-modulation.

This paper investigates the performance of a reflective semiconductor optical amplifier in a bidirectional wavelength-division multiplexed passive optical network at 2.5 and 5 Gbit/s over 20 and 15

Low linewidths for Al-free active region distributed feedback lasers using a self-heterodyne measurement method (minimum beat width of 0.8 MHz at 20 mW and 12 C, 1.2 MHz at 852.12 nm 35 mW and 36 C

SDL is the Specification and Description Language developed by the International Telegraph and Telephone Consultative Committee (CCITT).

A dynamically reconfigurable TDM-DWDM PON for converged multi-services at the physical layer (10G, 100G and wireless fronthaul) has been demonstrated for the first time implementing end-to-end SDN

Simultaneous operation of multiple services showing different modulation formats, multiplexing techniques and bitrates is experimentally demonstrated in an open converged metro-access infrastructur

We demonstrate 26 hours of error-free wavelength switching between 32 ITU channels in less than 50 ns using a GCSR laser.

We successfully fabricated submicron depletion-mode GaAs MOSFET's with negligible hysteresis and drift in drain current using Ga2O3(Gd2O3) as the gate oxide.

We demonstrated a symmetrical 25-Gbps TDM-PON with 31.5-dB optical power budget over 0-20-km at 1556-nm using only 10-Gbps optical components.
