Patent ID: 8780951

Claim:
A method of making a resonator, the method comprising: regulating a shutter action to fabricate a first multinary compound semiconductor layer, a second multinary compound semiconductor layer, and a third multinary compound semiconductor layer, using molecular beam epitaxy; providing an Al source shutter, set to provide a first predetermined growth rate; providing an As source shutter, set to provide a second predetermined growth rate; and providing a Ga source shutter, set to provide a third predetermined growth rate, wherein the ratio of thickness between the first and second multinary compound semiconductor layers determines the composition of a unit digital alloy multinary compound semiconductor layer; the thickness of the third multinary compound semiconductor layer determines the composition of a unit distributed Bragg's reflector (DBR); wherein the unit digital alloy multinary compound semiconductor layer is formed by combining the first and second multinary compound semiconductor layers; the unit distributed Bragg's reflector (DBR) is formed by comnining the unit digital alloy multinary compound semiconductor layer with the third multinary compound semiconductor layer; and wherein the As source shutter is configured to remain open while the Al and Ga source shutters are configured to alternate between open and close states, such that the Al and Ga sources are not opened at the same time.
