Ruth A Mullen: Opto-electronic membrane probe. Hughes Aircraft Company, V D Duraiswamy, W K Denson Low, December 10, 1996: US05583445 (101 worldwide citation)

A probe for testing very high frequency circuit chips (34) includes a flexible membrane (12) having test probe contacts (14), arranged to contact pads (32) on the device under test to bias up, drive and load down the circuit under test. Various optically-addressable devices (68,130,202) are mounted ...

An optical input beam is transmitted through a non-linear medium capable of two-wave mixing gain by photorefractive, Brillouin, Raman, or other non-linear optical mechanism. A psuedo-conjugator retroreflects the input beam which has passed through the medium, back into the medium. The retroreflected ...

Ronald I Wolfson, Ruth A Mullen, William W Milroy: Optically reconfigurable conductive line element. Hughes Electronics, Leonard A Alkov, Wanda K Denson Low, February 17, 1998: US05719975 (18 worldwide citation)

An optical fiber having a conductive layer disposed therearound has sections removed therefrom that form gaps that expose the underlying optical fiber. Light manifolds are formed at each gap, such as are provided by Bragg gratings photoinduced in the core at each gap, and photoconductive material is ...

Ruth A Mullen, Robert W Hellwarth: Electrical field quenching of optical breakdown. Hughes Aircraft Company, V D Duraiswamy, W K Denson Low, September 22, 1992: US05149406 (4 worldwide citation)

Optical breakdown in a transparent, non-linear medium used for optical phase conjugation or the like is induced by interaction with the medium of a strong laser beam propagating therethrough, resulting from electron avalanche breakdown and plasma formation. Application of an electrical potential to ...
