Coherent optical detection offers the potential to substantially increase the capabilities of existing long-haul and local area fiber-optic networks. however, random drift of the signal polarization presents the major obstacle to this method of detection. the objective of this proposed program is to… More

High density integration of external optical waveguide modulators that may be used effectively at bandwidths in excess of 30 ghz is to be investigated. this requires launching microwave modulation energy to the modulation transmission line with minimum radiated energy, interconnecting the… More

An external guided wave optical modulator which provides the combination of high bandwidth, low insertion loss, and linearity is being developed. researchers are designing, fabricating, and testing a novel multiple quantum well electroabsorption modulator. it operates at an optical wavelength of… More
