Abstract:

To make an optical device have an operating speed markedly faster than that of a conventional device.

When an optical device 11 is provided with an optical path area 13 where a light beam 24 transmits along an optical path 23, the optical path area 13 is provided with mutually separated first and second quantization well layers 35, 37. Moreover, the optical characteristic of the optical device 11 is made to be modulated by performing the transferring of carriers in between the quantum well layers 35, 37 while impressing a voltage on at least two gate electrodes 25, 29 provided at the outside.
