Optically controlled integrated current diode lasers

摘要

Integrated laser diode devices are disclosed in which small light signals or small current signals applied thereto produce large changes in the output. One embodiment discloses a homostructure optical device with symmetric optically excited regions. Another embodiment discloses a single-heterostructure optical device with a single optically excited region. Another embodiment discloses a double-heterostructure optical device with dual optically excited regions. A further embodiment integrates an electronic device with a diode laser in accordance with the principles of the present invention. Still another embodiment discloses an optical triode laser device in which a small input light results in an amplified light output signal.
