Novel laser for fiber‐optic communication

OCT 01, 1983

A new kind of semiconductor laser, developed by Won‐Tien Tsang and his colleagues at Bell Labs, has demonstrated a number of remarkable capabilities that promise to be of considerable importance for fiber‐optic communication. This cleaved‐coupled‐cavity semiconductor laser, nicknamed the C3 laser, is able to generate essentially monochromatic pulses of infrared light at repetition rates in excess of a gigahertz. Furthermore, one can electronically switch this pulsed monochromatic output from one wavelength to another on a nanosecond time scale.
