We have developed high-speed mid-infrared quantum cascade lasers with direct modulation bandwidth of approximately 7 GHz.
Optical-fiber communication systems that use L E D S as sources and PIN photodiodes as detectors offer the attractive features of reliability, simplicity, and low cost.
Two novelties have been exploited in developing high-speed directly-modulated distributed feedback and distributed Bragg reflector lasers: the use of surface gratings, to enable a single growth and
Due tot he need of operators to protect the high levels of investment in third generation (3G) wireless systems, it seems likely that the path to fourth generation (4G) wireless sytems will be evol
High-speed electrical data transmission through low cost backplanes is a particularly challenging problem.
Driven by increasing bandwidth demand from increasing broadband penetration, video, and other high-bandwidth services, the IEEE 802.3 working group has proposed a new project on higher speed Ethern
Describes a series of special gas tubes developed for telephone and telegraph switching during the period 1947-1957.
We describe a simple method and device design that enables fast in-plane electro-optic modulation in conventional nematic liquid crystal (NLC) devices.
Recently, the bandwidths of semiconductor lasers, detectors and optical transmission systems have been dramatically increased.
We present characteristics of InGaAsP electroabsorption modulators with variable length and mesa width.
