Wide Bandwidth, Low Loss 1 by 4 Wavelength Division Multiplexer on Silicon for Optical Interconnects
Wide Bandwidth Low Loss 1 by 4 Wavelength Division Multiplexer Silicon Optical Interconnects
2011/5/20
We demonstrate an add/drop filter based on coupled vertical gratings on silicon. The concept is extended to implement a 1 by 4 wavelength division multiplexer with 3nm bandwidth,1dB insertion loss and...
Experimental Investigation of Wide Bandwidth Single and Dual Pump non-Degenerate Phase Sensitive Amplifiers
Fiber optics amplifiers oscillators Nonlinear optics parametric processes
2010/6/10
We demonstrate non-degenerate phase sensitive amplification of a DPSK data signal in both single and double pumped parametric configurations, achieving uniform phase sensitive gain and attenuation ove...
High Order Cascade Multibit ΣΔ Modulator for Wide Bandwidth Applications
behavioural study DAC nonlinearity DEM VHDL-AMS modelling
2007/1/30
A wideband 2-1-1 cascaded ΣΔ modulator with a
single-bit quantizer in the two first stages and a 4-bit quantizer in the
final stage is developed. To reduce sensitivity of digital-to-analog
converte...
Wide bandwidth, large, and tunable polarization mode dispersions in multilayered omnidirectional reflectors
Wide bandwidth tunable polarization mode dispersions multilayered omnidirectional
2002/8/11
We numerically demonstrate the generation of large, broadband, and tunable polarization mode dispersion ~PMD! with omnidirectionally reflecting dielectric stacks with embedded cavities. Both ...
