LOGIC ELEMENT DISPLAYING BISTABILITY OF LIGHT WITHOUT APPLIED VOLTAGE FROM OUTSIDE AND ITS MANUFACTURE

摘要

PURPOSE: To improve bi-stability of light in SEED where the bi-stable characteristic of light is obtained with improvement without external voltage. CONSTITUTION: The thickness of an intrinsic area is reduced by appropriately reducing the frequency of a multiplex quantum well 31. Thus, SEED of an asymmetrical Fabry rot structure where resistance for considerably increasing the difference (ΔR) of a reflection factor between on/off states and the bi-stable width (ΔP) of light does not match while the appropriate on/off intensity ratio is maintained which is required from an optical system can be provided.
