Patent Number Title Of Patent Date Issued
4720163 Laser-fiber positioner January 19, 1988
To position a light output device such as a laser diode relative to a light device such as a waveguide so as to obtain maximum coupling of light, the waveguide end facing the laser is vibrated by mechanical means to modulate the coupled light. Light is detected from a remote end of the f
4489477 Method for screening laser diodes December 25, 1984
A method for screening double heterostructure laser diodes before mounting and packaging is disclosed. At a normal laser diode operating temperature, a range of pulsed current is passed through the laser diode and the lasing threshold current and slope efficiency of the laser diode are m
4483541 Gas seal for semiconductor processing equipment November 20, 1984
During production of laser diodes, crystals on which the laser diodes are formed are subjected to two high temperature processes: diffusion and alloying. These steps are performed in a quartz process tube in an oxygen free atmosphere. At some stage in the process the crystal must be move
4399541 Light emitting device package having combined heater/cooler August 16, 1983
A known electro-optic has a semiconductor laser, a temperature sensor for controlling an electrically operated cooler, and an optical fiber end portion anchored close to the laser to receive light from it. Usually the fiber is anchored by a mass of cured epoxy. This invention proposes
4389557 Semiconductor laser bonding technique June 21, 1983
In a method and apparatus for bonding a semiconductor laser chip to a heatsink and testing the bond obtained, temperature in the bonding operation is regulated by passing a small fixed current through the forward biased laser and monitoring corresponding change in voltage caused by a
