Abstract

A flexible continuous optical beamformer with time delay for a phased‐array antenna is proposed and demonstrated. It is constructed using a novel tunable chirped fiber grating achieved by bending a uniform grating, and a multi‐wavelength fiber laser based on a novel Sagnac interferemetric filter that consists of a polarization‐maintaining directional coupler and polarization‐maintaining fibers. © 2003 Wiley Periodicals, Inc.

dition. The reflection boundary condition (RBC) and the absorbing boundary condition (ABC) are examples of such velocity boundaries that have been investigated with the problem of synthesizing a rectangular deep null in the sidelobe region. The obtained results show that by using an RBC or ABC, and
