ABSTRACT:
A photo-induced electro-optic oscillator using a multiple quantum well structure PIN diode using a negative resistance characteristic of a photocurrent-voltage is disclosed. The present invention can generate the modulated optical signal as well as the electrical AC signal of a high output by using the multiple quantum well structure having the electro-absorption as the intrinsic layer of the PIN diode, regulate the electrical AC signal frequency and signal amplitude by means of regulating the PIN diode and electrical elements, regulate the modulated optical signal frequency and the modulated signal difference and extinction ratio by means of regulating the multiple quantum well structure, as a result, to generate the electrical and optical signal of a high output, high frequency.
