Patent Number Title Of Patent Date Issued
4530099 Planar narrow-stripe laser with improved charge carrier confinement July 16, 1985
Double heterostructure lasers which use a narrow stripe contact exhibit linear characteristics with a low lasing threshold current making them very suitable for fiber optic communication systems. Linearity and low threshold currents are achieved if the carrier current injected into the
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
4297651 Methods for simultaneous suppression of laser pulsations and continuous monitoring of output pow October 27, 1981
Semiconductor lasers exhibit transient relaxation oscillations on start-up and specific lasers often exhibit sustained spontaneous pulsations caused probably by crystalline defects. These fluctuations are suppressed by coupling laser emission into a 0.3 to 2 cm. length of waveguide and
