Abstract

This invention relates to an optical device for manipulating an optical signal propagating in a waveguide; and to a multiplexer, an attenuator and a modulator incorporating such device. A device according to the invention comprises two superimposed and tilted reflectors within the waveguide, which reflectors are arranged to deflect light out from the waveguide in two individual, substantially counter-propagating beams. The device according to the invention allows manipulation of individual channels within a wavelength dividion multiplexed optical signal. In a preferred embodiment, light is deflected out from the waveguide and into an external Fabry-Perot type resonator, which is tuned and adjusted in order to manipulate individual wavelengh regions of light. The invention also relates to a method for manipulating an optical signal, and to a method of tuning an optical device according to the invention.
