Latest Patents

One of his latest patents is an optical transmitter and optical transmitting apparatus utilizing Passive Double Star (PDS) technology. This innovative optical transmitter is designed to prevent erroneous optical signal outputs when powered on or off. The device features a current source that outputs a drive current corresponding to an input control signal. It includes a laser diode (LD) that generates an optical output signal based on the received drive current. Additionally, a modulator controls the supply and cutoff of the drive current to the laser diode. A source voltage detector monitors the source voltage to ensure it does not fall below a predetermined level. If the voltage is too low, a switch circuit sends a control signal to the current source to halt the drive current supply.
