Abstract
Optical ADD/DROP multiplexers (OADM) are incorporated into all-optical network structures that provide fixed access to a subset of the wavelengths in Wavelength Division Multiplexer (WDM) systems. The rapid growth of broadband data communications and the drive toward cost reduction have made optical MEMS (Micro- Electro-Mechanical Systems) an extremely attractive technology for applications in optical communications. This paper will present theoretical analysis, simulation and testing results of an ADD/DROP multiplexer based on the MEMS-based micro-actuators. The micro-actuator is a MEMS-based compound grating (MCG) with a reconfigurable surface that couples the mechanical motion with optical diffraction. The diffraction patterns depend on the wavelength, incident angle and the grating structural parameters. This property is used to design an OADM that can be applied to broad areas in optical communication. A theoretical analysis is presented to establish the relationship between diffraction beams and the structural parameters of the grating, the wavelength of incident light, incident angle. Prototypes of these micro-actuators have been fabricated. The initial testing demonstrated the feasibility of using the MCG as an OADM. New designs of the MCG for application to the 1.55um optical telecommunication standard will be discussed.
