Abstract

A device for spatially separating components of frequency in a primary radiation beam comprising means (40) for separating the primary radiation beam into a plurality of secondary radiation beams, a plurality of electrically biasable waveguides (41) forming a waveguide array, each for transmitting a secondary radiation beam to an output, wherein each waveguide has an associated optical delay line (43) having a corresponding optical delay time, wherein each of the optical delay times is different. The device also comprises means (42) for applying a variable electric field across each of the waveguides such that the phase of the secondary radiation beams (45) transmitted through each may be varied by varying the electric field. The secondary radiation beams output from each of the waveguides interfere in a propagation region with a secondary radiation beam output from at least one of the other waveguides so as to form an interference pattern comprising one or more maximum at various positions in the propagation region. Preferably, the device provides at least two outputs. The device may also comprise means for applying RF modulation to the primary radiation beam. The device may comprise electrically biasable GaAs waveguides formed in one with the associated optical delay lines on a single chip. Alternatively, the device may comprise an array of electrically biasable waveguides each having an optical fibre delay line. The device may be used as a staring spectrum analyser for optical or microwave frequencies for demultiplexing or multiplexing a beam of radiation and for controlling the wavelength of a tuneable on-chip laser.
