ABSTRACT:
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.
