  • Opto-electronic circuits and techniques
    Patent number: 9452928
    Abstract: A hybrid circuit for producing optical signals in response to electrical energizing signals, including: a tilted charge light-emitting device having an electrical input port and an optical output port, the device having an optical output response which is a function of input frequency; and an input interface circuit coupled with the electrical input port of the device, and having a transfer function substantially proportional to an inverse of the optical output response of the device; whereby application of the electrical energizing signals to the input interface circuit is operative to produce optical signals from the output optical port of the device. The input interface circuit includes a passive RLC circuit having a transfer function characterized by a region of increasing amplitude versus frequency.
