We investigate optical bistability in intersubband transitions of an asymmetric semiconductor quantum well structure that has equidistant transitions between three subbands of the system and is placed in a unidirectional cavity. The system is simultaneously coupled by a fundamental field and its second harmonic. The second harmonic field acts as a control field and significantly influences the optical bistability. In addition, the two-color coherent control of optical bistability by the relative phase of the fundamental and the second harmonic fields is shown. The influence of the electronic cooperation parameter on the OB behavior is also discussed. This investigation may be used for optimizing and controlling the optical switching process in the SQW solid-state system, which is much more practical than that in the atomic system because of its flexible design and the controllable interference strength.

ABSTRACTWe have performed investigations of resonance effects inside a gallium nitride one-dimensional photonic crystal slab in order to enhance the second-harmonic generated from an beam incident on the surface of the slab. Convenient conditions on the incident beam propagation direction and polarization are first identified by experimental or theoretical linear optical studies. Giant enhancements in the second-harmonic conversion have been obtained by comparison with the unpatterned GaN layer. The combined role of the resonant coupling of the fundamental field and of the second-harmonic field has been observed by rotating the polarization of the fundamental beam.

Under the non-resonant condition, we investigated the optical bistability (OB) in a three-level quantum well system inside a unidirectional ring cavity. We find that the incoherent pumping fields and the quantum interference induced by incoherent pumping fields can affect the optical bistability dramatically, which can be used to manipulate efficiently the threshold intensity and the hysteresis loop. These results are achieved by applying the two incoherent pumping fields, so they are very different from the conventional schemes that coherent driving fields are used to control the optical bistability. Thus, it may provide some new possibilities for technological applications in optoelectronics and solid-state quantum information science.
