摘要： An integrated optical package comprises an integrated optical device supported on a carrier with a gelatinous material therebetween to assist in heat conduction. The carrier can include a thermal regulating device such as a heat sink or heater for regulating the temperature of the integrated optical device via the gelatinous material. The gelatinous material can include a metallic second phase suspended in the gelatinous material, to improve its thermal conductivity. The maximum dimension of the particles is ideally smaller than the gap between the integrated optical device and the carrier in which the gelatinous material is located, such as in the 5 to 95 percent range of the dimension of the gap. The particles of the metallic second phase can be elongate, in which case they can be aligned with each other such as in a direction extending from the integrated optical device towards the carrier. Alternatively, they can be substantially spherical. Ferromagnetic particles are easier to align by using a magnetic field. A method is also disclosed, comprising the steps of disposing a closed loop of adhesive, thus forming a well, on one or the other of the integrated optical device or the carrier, placing a gelatinous material into said well, placing the other of the carrier or integrated optical device in contact with the adhesive layer and gelatinous material, and curing the adhesive to secure the integrated optical device to the carrier. The gelatinous material can be thixotropic.

摘要： An arrangement of an integrated optical waveguide (1) relative to a V-groove (2) for receiving an optical fibre (5) which is to be optically coupled with an end of the waveguide (1) is described. A waveguide (1) is formed in a crystalline optical substrate (3), and a V-groove (2) formed therein beneath an elongate parallel sided window in the substrate with a centre line (2A) of the V-groove (2) aligned with an end (1A) of the waveguide (1). The parallel sides (2B, 2C) of the window at the end of the V-groove (2) aligned with the waveguide (1) terminate out of alignment with each other in a direction along the length of the V-groove whereby the V-groove undercuts a portion (3A) of the optically conducting layer (3) beneath said end of the waveguide (1). The end of the waveguide (1) therefore overhangs the end of the V-groove (2) to enable the end of an optical fibre (5) to be located in close proximity thereto.

摘要： A fiber block for connecting optical fibers to an optical device comprises a lithographically defined front face and a plurality of recesses for optical fibers extending linearly from the front face in a plane which is substantially perpendicular to the front face, at an angle within that plane which is non-perpendicular to the front face. It is preferred that the block is essentially rectangular with recesses for the optical fiber formed in it in a non-perpendicular arrangement. The block is preferably formed as two mating parts each with aligned recesses on their mating faces, thereby to permit an optical fiber to be held in a pair of recesses one on each part. The recesses can end with a locally narrower portion which acts as an end stop for the fiber thereby to permit it to be located accurately. The recesses are preferably V-grooves and the block is preferably of silicon. A method of forming a fiber block is also disclosed, consisting of the steps of lithographically defining at least one edge thereof, lithographically defining a recess for seating an optical fiber, the recess extending to the edge, wherein the recess subtends an angle at the edge which is non-perpendicular.
