Abstract
An optical device for multiplexing/demultiplexing optical wavelength signals comprises arrayed waveguide grating devices. To one thereof an optical signal, e.g. one of the optical wavelength signals or an optical signal from a reference source, is input so that its corresponding output signal can be used as a temperature control signal for a temperature control means of the waveguide device. Thus optimization for one optical wavelength signal automatically leads to optimization of all other optical wavelength signals.
Claims19
An optical device for multiplexing/demultiplexing optical wavelength signals, comprising phased array waveguide devices, characterized in that the optical device comprises waveguide device temperature control means having a temperature control input, whereby an optical signal is input to one of the phased array waveguide devices, whose output is coupled to the temperature control input of the temperature control means.
An optical device, comprising:
- a substrate;
- a first waveguide structure coupled to the substrate;
- a second waveguide structure coupled to the substrate;
- a first phased array waveguide device coupled to the first and second waveguide structures and disposed between the first and second waveguide structures,
- a second phased array waveguide device coupled to the first and second waveguide structures and disposed between the first and second waveguide structures, wherein the second phased array waveguide device is adapted to have an optical signal pass through the second phased array waveguide device, and wherein a temperature of the substrate is controllable in dependence on an amplitude of the optical signal.
