We proposed a regenerator for dual polarization QAM systems applying oeo conversion and regeneration in the digital domain without intermediate FEC.
Faint galaxies and stars of 27 V magnitude are detected in 2 hours integration on a 4 meter telescope. This corresponds to 2 photons/sec.
Abstract Experimental results using the amplified spontaneous emission (ASE) spectroscopy of a type-I quantum-cascade (QC) laser are presented.
We report absorption loss coefficients at 1550 nm of free-standing GaN grown by hydride vapor phase epitaxy.
An optical electroabsorption waveguide modulator is described based on the quantum confined Stark effect in an InGaAs/InP multiple quantum well (MQW) waveguide.
Double heterostructure planer waveguides with InGaAs/InP multiple quantum well (MQW) core and InP cladding layers were grown by atmospheric pressure MOCVD.
We have developed an optical integrated circuit waveguide technology based on conventional Si processing.
A 9-channel grating single-mode wavelength-division multiplexing scheme is demonstrated at 1.5micron with the lowest insertion loss reported to date.
Many practical integrated optical LiNbO(3) devices, such as NxN switch arrays, operate on TM polarized light in Z-cut crystals to utilize the largest electro-optic coefficient, r(33).
We present an ultra broad band wavelength selective switch with 15 THz of bandwidth and less the 4dB insertion loss.
