Abstract
An AWG device includes a plurality of arrayed waveguides positioned close to each other. An input signal excites one of these coupled waveguides and the power is then transferred to all of the arrayed waveguides so there are enough degrees of freedom in the device to achieve any desired distribution.
Claims12
An arrayed waveguide grating (AWG) device comprising:
- a plurality of arrayed waveguides positioned close to each other so that an input signal excites one of these coupled waveguides and the power is then transferred to all of said arrayed waveguides so there are enough degrees of freedom in the device to achieve any desired distribution.
A method of performing an arrayed waveguide grating (AWG)-based operations on an input signal comprising:
- providing a plurality of arrayed waveguides positioned close to each other so there are enough degrees of freedom to achieve any desired distribution;
- and
- exciting one of these arrayed waveguides using said input signal so the power is then transferred to all of said arrayed waveguides.
