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 |

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 |

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 |

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 |
