Abstract
We propose a new structure for the integrated laser Doppler blood flowmeter which consists of a Si cavity and a photodiode and a laser diode within the cavity. A silicon cover formed with a converging microlens also functions as the package. This structure has a reduced rate of optical power loss in the sensor, resulting in significantly low power consumption.
