| | Mach-Zehnder interferometers employing semiconductor quantum heterostructures as nonliner media(Fig.1) are quite versatile because they can be applied for all-optical processing such as all-optical switching, wavelength conversion, and add-drop multiplexing. We have been investigating the following two approaches toward all-optical processing. |
