摘要： An integrated optical waveguide (70) having an in-line light sensor (70a, 71a, 72a) integrally formed therewith for tapping off a small proportion of the signal transmitted along the waveguide (70). A first part of the waveguide leads to a photodiode portion (70a, 71a, 72a) and a second part of the waveguide leads away from the photodiode portion, the photodiode portion comprising one or more regions of light absorbing material within the waveguide arranged to absorb a minor proportion of light transmitted along the waveguide and thereby to generate free charge carriers within the waveguide. Deep band gap levels are introduced into photodiode portion by ion implantation to enable it to absorb selected wavelengths. The free charge carriers are detected by a p-i-n diode formed across the waveguide. Wavelength selective reflectors (11, 12) may be provided either side of the photodiode portion so light passes repeatedly through the photodiode portion.

摘要： A waveguide is formed by using a single mask to define waveguide features and alignment features on the core layer. Etch stop is retained on the alignment features when the cladding layer is added and a second mask defined which defines a mechanical stop and a waveguide facet aligned to the stop. The mask area is etched down to the substrate apart from the protected alignment features. Laser and other components can be attached. Lasers may be attached by solder bumps and have their own alignment feature spaced from the laser facet.

摘要： Optical routing apparatus comprises input waveguides (2) for receiving optical input signals incorporating identifying signals applied by VOAs (4), and beam steering arrangements (5) for directing the input signals towards selected output waveguides (3). A sample of each output signal is tapped off and supplied to a respective photodetector (7). The electrical output signal of the photodetector (7) is supplied to a processor 8 which detects the presence of the required identifying signal in the sample and provides a feedback signal to a steering controller (9). The steering controller (9) controls the steering arrangements (5) in dependence on the feedback signal so as to direct each input signal towards the selected output as determined by detection of the corresponding identifying signal at that output. Such an arrangement enables a selected one of the inputs of an nxn optical switch, for example, to be placed in optical communication with a selected one of the outputs of the switch with optimal beam steering.
