A glass-fiber optical channel for the transmission of nanosecond pulsed signals
Abstract
The article deals with the design of a widebanded optical transmission line for the nanosecond pulse range. A double heterostructure GaAs injection laser launches coherent radiation into the fiber line; the laser heterostructures are produced via liquid epitaxy. The single-core glass-fiber cableware, the fabrication method for the low-loss fiber material, matching of the glass fiber to the laser and photodetector via a glycerin immersion layer, the 7-stage wideband amplifier designed around bipolar microwave transistors, fabrication of stripline contacts, laser pulse parameters, and fiber core refractive index grading are described.
