High-Efficiency Polarized Light Illumination System for Liquid-Crystal-Display Projectors
liquid crystal display illumination system projector polarization conversion shape conversion offset design
2011/11/30
We present a new optical system with two identical s- and p-polarized light paths for converting a random polarized beam into a linearly polarized one. The system also provides a uniform and rectangul...

This paper evaluates the energy-savingachievable by performingtraffic grooming in WDM networks with drop-and-continue node architecture. Different grooming strategies are compared in terms of network ...
Coherent 40 Gb/s Transmission with High Spectral Efficiency Over Transpacific Distance
Coherent 40 Gb/s Transmission High Spectral Efficiency
2015/5/20
We experimentally study the reach of coherent 40 Gb/s PDM RZ QPSK transmission at several spectral efficiencies. Transpacific transmission distance at 3.2 bits/s/Hz and record SE-distance product at 2...

Spectrum-Efficiency Bandwidth-Variable Optical OFDM Transport Networks
2015/6/10
We investigated the high spectrum efficiency property of the bandwidth-variable optical OFDM (BV-OOFDM) transport networks. In contrast to mixed-line-rate (MLR) networks, BV-OOFDM enables flexible all...
Long-haul coherent QPSK transmission of 40G channels with 120% spectral efficiency using increased linearity dispersion map with 100km spans and EDFAs
