An MOS (metal oxide semiconductor) photon-assisted tunneling (PAT) device 10 in Fig. 1 is used in Fig. 2 as an optical FM demodulator of FM-modulated light beam 13 of frequency w = w(o) + w(t), where w(o) is a constant light frequency and w(t) is a variable light frequency which varies as a function of time.
