摘要： A hybrid optical component is described incorporating a planar lightguide circuit (PLC) chip 2 having at least two waveguides provided thereon which are separated by a trench, and a MEMS chip 3 attached to the PLC chip and incorporating a MEMS element displaceable relative to the trench so as to control the passage of an optical signal between the two waveguides. A cap 4 is sealingly engaged with the PLC chip 2 to form a housing therewith which houses said MEMS chip 3 hermetically therein. The component may act as a variable optical attenuator (VOA) device in which a MEMS shutter attenuates an optical signal passing between two waveguides, or may be an optical switch in which a MEMS mirror is used to switch an optical signal from a first waveguide between at least two other waveguides which intersect with the first waveguide at the trench.

摘要： A passband-flattened phasar including two free space regions (48, 52) coupled by a plurality of waveguides (50) having predetermined differences between their lengths so as to act as an arrayed waveguide grating. The phasar is particularly useful in a wavelength-division multiplexed (WDM) optical communication system. The input waveguide is coupled to the first free space region through a Mach-Zehnder interferometer (MZI) (64) having two waveguide arms (66, 68) of differing lengths receiving approximately equal amounts of the input signal. The arms differ in lengths so as to produce a phase difference between them. In WDM network, the waveguide arm produces a phase difference such that the free spectral range of the MZI equals the wavelength channel spacing, such that the wavelength response of the MZI is the same for each of the WDM wavelengths. The two outputs of the MZI are coupled into the input end of a multi-mode interferometer (MMI) (44) with a lateral separation which provides a lateral spatial dispersion in the MMI equalling the lateral spatial dispersion of the conventional phasar. Thereby, a larger portion of the passband is equally passed through the phasar.

摘要： An arrayed waveguide grating (AWG) device is described in which there are a plurality of output waveguides (10) coupled at one end to the output side of an second optical interaction region (4) of the AWG, and wherein the output waveguides are substantially identically curved in at least a portion of the fan-out region of the AWG. This improves the channel (frequency) spacing accuracy of the AWG. In one embodiment input waveguides (2) of the AWG are also substantially identically curved in at least a portion of the fan-in region of the AWG, these being inversely curved to the substantially identically curved portions of the output waveguides, with respect to the direction of travel of light along the waveguides. This has been found to reduce asymmetry in the channel output response.

摘要： In an arrayed waveguide grating (AWG) comprising fist and second slab waveguides and an array of waveguides optically coupled therebetween, the angle of the array waveguides at the slab waveguides is chirped according to the following equation: θ i = ArcSine ( i .Δθ), where i = -(N-1)/2, -(N-1)/2 +1, ..., +(N-1)/2 where i is the array waveguide number, N is the number of array waveguides, and Δθ is a constant. The chirping removes third-order aberration (COMA) which would otherwise cause asymmetry in the AWG output channel signals, especially where the AWG has a flattened passband.
