Abstract
An optical biosensor is provided. The optical biosensor includes a biosensing unit, a detection unit, and a feedback circuit. The biosensing unit is configured to receive an input optical signal, sense a biomaterial, and generate a sensed optical signal. The detecting unit is configured to convert the sensed optical signal into an electrical signal and output the electrical signal as a detection signal. The feedback circuit is configured to output a feedback signal. The feedback signal is generated based on the detection signal and is changed according to a changed amount of a resonant wavelength of the biosensing unit.
