Latest Patents

Nagao's latest patents include an optical bistable device and a light signal binary device with optical feedback. The optical bistable device is integrated onto a semiconductor chip and features a photoresponsive element that receives an input light signal. This device is designed to produce a reverse current in the photoresponsive element, which leads to light emission. The positive feedback mechanism allows for a transition from low to high light output at a specific input light change value. Additionally, a light modulator is incorporated to adjust the amount of light received by the photoresponsive element.

The light signal binary device with optical feedback utilizes an input optical fiber to guide a light signal to a light receiving element, converting it into an electric signal. This electric signal is then transformed back into an optical signal by a light emitting element. The optical signal is positively fed back to the light receiving element through a partially reflecting film, enabling the input optical signal to be converted into a two-valued state at the output side.
