Abstract
The authors propose a new scheme for a non-biased all-optical oscillator based on the anti-parallel connection of two GaAs/AlGaAs multiple shallow-quantum well p-i-n-i-p (PINIP) diodes. Under the illumination of 3 mW lasers, the oscillator revealed the electrical and optical oscillations with a frequency of ~43.8 MHz. The intensity oscillations in the reflected beams from the two diodes showed a phase difference of π, an on/off reflection change of ~22%, and a contrast ratio of ~2
