Optimum diameter for laser beam and effect of temperature rise on the optical bistability hysteresis loops

Abstract EN

In this research, analytical study for simulating a Fabry-Perot bistable etalon (F-P cavity) filled with a dispersive optimized nonlinear optical material (Kerr type) such as semiconductors Indium Antimonide (InSb).

An optimization procedure using reflective (~85%) InSb etalon (~50µm) thick is described.

For this etalon with a (50 µm) spot diameter beam, the minimum switching power is (~0.

078 mW) and switching time is (~150 ns), leading to a switching energy of (~11.

77 pJ) for this device.

Also, the main role played by the temperature to change the etalon characteristic from nonlinear to linear dynamics.
