Abstract:
The invention relates to a coupling location (11) which can for example be used to couple light (31) emitted by a diode (21) into an optical waveguide (15). According to the invention, the light-emitting diode (21) is aligned at stop surfaces (22) in such a manner that the coupling of light is facilitated with high precision along an axis of transmission (30). The optical fibers (33) in the optical waveguide (15) are advantageously coaxially disposed around a core (34) that is impervious to light so that said core is illuminated with comparable light intensity taking into consideration the light intensity distribution (31) of the light-emitting diode (21) which is configured as a Gaussian emitter.
Abstract:
An optical coupling mount for use in coupling light between a semiconductor waveguide device and an optical fibre comprises a silica based spot size converter located on an optical bench with fiducial marks and protrusions, whereby the semiconductor device can be positioned in close alignment with the spot size converter. The spot size converter comprises a tapered upper waveguide located above a non-tapered lower waveguide. The dimensions of the spot size converter are such that a semiconductor device emitting a small, astigmatic optical beam can be efficiently coupled to a single mode fibre requiring a larger, concentric beam. Also provided is a thermal backplate with electrical routing patterns and which, when assembled with the optical bench, contact both the semiconductor device and corresponding electrical routing patterns on the optical bench, thereby providing a mechanically robust device with provision for simple connection to an external electrical power supply.

Abstract:
The present invention provides a method and apparatus for reception of optical communication (100). The present invention provides an optical receiver (170) that includes a feedback circuit to enhance the stability of output power levels, and an electrode structure (352) that facilitates high frequency optical signal detection. The electrode structure (352) is designed for ease of fabrication. These features allow the receiver (170) to receive an optical output beam that can be modulated over a wide range of frequencies, duty cycles and amplitudes with the receiver providing very precise definition of the rising and falling edges of the information carried on that output beam. A novel transmitter (140) for use in conjunction with the receiver is also disclosed.
