The frequency-dependent distortion of composite triple beat (CTB) for analog AM multichannel lightwave transmission systems is studied. A modified circuit model which takes into account the small signal behavior of the leakage path is developed, and

The end-to-end bit-error performance of 64-QAM transmission using a hybrid fiber-coax system test bed designed for delivery of 77 AM-VSB and 25 64-QAM video channels covering the frequency band 54 - 702 MHz was studied. Error-free QAM transmission wa

Intense interest has been generated by the possibility of transmitting multiple AM-VSB NTSC signals over optical fiber. However, noise and distortion levels have not been consistent with objectives for signal quality in the CATV trunking application.

A DFB laser has been packaged using an optical design consisting of two lens elements placed in quasiconfocal arrangement to accommodate an optical isolator. The first element is a plano-convex silicon lens with a radius and thickness of 0.875 and 1.

The composite triple beat (CTB) is an important parameter for describing the third-order distortion in a lightwave CATV transmission system. It is also a main concern of distortion in a one-octave load system. The typical specification for CATV appli

The optical absorption, photoconductivity, contact photovoltage, electrical conductivity, and Hall coefficient of single crystals of WSe2 have been studied over the temperature range 77°–295°K. It was found that the forbidden energy gap Eg was 1.
