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.
A cost effective symmetrical 25 Gbps TDM-PON utilizing a novel multilevel user-interleaving scheme based on PAM-4 in the downstream and 3-level duobinary modulation in the upstream is demonstrated
We demonstrate a new architecture that overcomes the bandwidth bottleneck of SONET rings with high node count by allocating different WDM channels for each receiving node and transmitting time-mult
