摘要： The invention relates to an electroabsorption modulator (EAM) (300), comprising a first EAM section (302) optically coupled to a second EAM section (304), a transition wavelength in the electroabsorption (EA) spectrum of the first EAM section (302), at which absorption changes substantially, being different to a transition wavelength in the EA spectrum of the second EAM section (304). The EAM (300) compensates for chirp (which is caused by intrinsic absorption effects) by driving the two sections with a signal (312) generated from a common modulating signal (314). The driving signal (312) at the first EAM section (302) being preferably in anti-phase with the driving signal (312) at the second EAM section (304).

摘要： Disclosed is a method for forming a first optical device and a vertical stand-off on adjacent regions of a substrate. The method comprises the steps of: depositing subsequent layers of optical materials on the substrate and defining features of the optical device by masking and etching regions of at least one layer; defining the transverse extent of the stand-off by protectively masking a separate region of the or each layer that is etched; modifying the relative thickness of an upper section of the stand-off and the first optical device so that a second optical device subsequently supported by the stand-off is in close optical alignment with the first optical device; and etching a trench through one or more layers of material between the vertical stand-off and the first optical device. Also disclosed is an optical assembly comprising a first optical device and at least one vertical stand-off formed on adjacent regions of a substrate.

摘要： In the present invention, profiling of the end facet of an optical waveguide reduces the amount of reflected light propagating in the waveguide. In a conventional waveguide, the effective reflectivity experienced by light at a facet is determined by the modal content of the light and the refractive index of the waveguide (core and cladding) and other material at either side of the dielectric interface, which constitutes the facet. In the present invention, depending upon the modal content of the light, the waveguide dimensions and the refractive indices at the dielectric interfaces, we adjust the profile of the facets so that it is no longer planar and so substantially reduce the amount of reflected light propagating back along the waveguide. This reduction in "effective reflectivity" can be due to an increase in the loss experienced by any reflected light or due to an increase in the amount of light transmitted.

摘要： A mode field adapter (MFA) is disclosed. The MFA is tapered and includes a passive core region and an active core region separated by a distance. Further, the passive core region includes first and second passive layers that are separated by another distance. The MFA is configured to receive an optical signal from a first waveguide, and alter, for transmission to a second waveguide, an optical mode of the optical signal. The optical mode is altered based on the distance between the first and second passive layers, the distance between the active and passive core regions, and the tapering of the MFA. The optical mode is altered such that an optical loss associated with the optical signal traversing from the first waveguide to the second waveguide by way of the MFA is within a tolerance limit.

摘要： There is provided a superluminescent diode (SLD) comprising a planar optical waveguide (41) having two trenches (42) which extend from a facet (45) of the planar optical waveguide, the two trenches defining a ridge therebetween in the planar optical waveguide. At least one trench has at least a region (43) which is tapered, in which the width of the trench decreases with distance from the facet measured along the length of the trench. The tapering trench or trenches provide for light that is propagating away from the facet and guided by the ridge to be gradually evanescently coupled out to a surrounding broad area waveguide, thus reducing the amount of light that may reach a further facet and be reflected back into the guided mode.

摘要： According to the present invention, a travelling-wave electroabsorption modulator (TW-EAM) comprises: an optical waveguide with a plurality of adjacent regions electrically isolated from each other, the regions being characterized alternately by the properties of electroabsorption (EA) and optical transparency over the same range of optical wavelengths, and a microwave transmission line located above the optical waveguide, such that sections of the transmission line located above EA regions in the optical waveguide are in electrical contact with said EA regions, whereas sections of the transmission line located above transparent regions in the optical waveguide are electrically isolated from said transparent regions. In the absence of a microwave signal, the EA regions are substantially transparent to light in the optical waveguide. When a microwave signal is applied to the EA regions, they become substantially absorbing at the wavelength of the light in the optical waveguide. Thus, by applying a fast time-varying microwave signal to the transmission line, the absorption of light in the waveguide can be modulated temporally, thereby encoding information onto the light beam.

摘要： In the present invention, the or each facet of an optical device is defined on a wafer and then optically coated, prior to separation of the device from the rest of the wafer, which may contain other optical devices whose facets have been processed in the same manner. Thus, the facets of many optical devices may simultaneously be defined by an etching process and then optically coated, whilst the devices form part of the wafer. This approach provides for ease of multiple device manufacture at a lower cost. Furthermore, the etching and coating processes can be performed in the same controlled environment, preferably a vacuum, before the wafer is removed to be diced up into individual optical devices.
