Patent ID: 7589329

Claim:
An optical sensor, comprising: a substrate with a surface and an internal region; a shell disposed above the substrate surface, the shell operable to receive incident light emitted by a remote light source, the incident light characterized by at least one first wavelength; a beam disposed below the shell; a photodiode on the substrate surface below the beam, which photodiode, in response to receiving a first portion of the incident light, is operable to generate a charge on the beam such that a motion is induced in the beam to cause the beam to resonate; and a phosphor embedded in the substrate internal region below the photodiode and operable to receive a second portion of the incident light, the phosphor being further operable to emit light characterized by at least one second wavelength that is different from the first wavelength of the incident light, the phosphor emitted light being transmitted through the photodiode, the beam, and the shell.
