Herbert G. Koenig, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4393393
    Abstract: A laser diode is soldered between metal plates for intimate thermal and electrical contact. The plates are prefabricated and are provided with an insulative spacer therebetween. The two metal plates are held together in a preferred orientation by the spacer which is firmly adhered and sealed to the two plates during the diode soldering operation. The metal plates are constructed from material thin enough that they yield under thermal pressure of the diode to eliminate mechanical strain on the diode during thermal cycling. Backup plates are provided in contact with the diode mounting plates to feed electrical energy thereto.
    Type: Grant

  • Patent number: 4380075
    Abstract: High power operation in conjunction with excellent mode stability is rendered possible by a unique configuration comprising the use of two injection laser diode sections in a crossed-junction configuration.

  • Patent number: 4315225
    Abstract: A laser diode is soldered between metal plates for intimate thermal and electrical contact. The plates are prefabricated and are provided with an insulated spacer therebetween. The two metal plates are held together in a preferred orientation by the spacer which is firmly adhered and sealed to the two plates during the diode soldering operation. The laser diodes so mounted can be tested in this configuration and after testing are formed into an array by stacking the laser diode subassemblies providing spacer elements therebetween and series contacts from one end to the other of the array so that an array of laser diodes with matched characteristics can be constructed in a line which may not be in alignment with the total package to provide an intense light output at a predetermined wavelength.

  • Patent number: 4284963
    Abstract: A laser diode suitable for integrated and fiber optic applications requiring single transverse and single longitudinal mode operation. The single transverse mode is provided by making a gallium arsenide double heterostructural laser diode with a narrow stripe width and a relatively long length. The single longitudinal mode operation is provided by cracking the diode transverse to the stripe at one or more locations to form internal etalons in the laser cavity.
