An integrated optical package has an integrated optical device 1 which is preferably a silicon-on-insulator device supported on a carrier such as ceramic substrate 2 with a gelatinous material 3 between them to assist in heat conduction. The carrier can include a thermal regulating device such as a heat sink or heating elements 4 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. The device is made by 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 form adhesive side walls 5 and secure the integrated optical device to the carrier. The gelatinous material can be thixotropic i.e. the viscosity increases as the shear rate decreases. |
