WAVELENGTH SELECTIVE SWITCHING APPARATUS AND RELATED METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18239482 titled 'WAVELENGTH SELECTIVE SWITCHING APPARATUS AND RELATED METHOD
Simplified Explanation
The present disclosure describes a wavelength selective switching apparatus and method. The apparatus includes input and output ports, a dispersion assembly, a first-band filter, and a light redirection device.
- The apparatus disperses received optical signals into sub-signals in a dispersion plane.
- The first-band filter reflects first optical sub-signals and transmits second optical sub-signals.
- The light redirection device redirects sub-band optical signals towards the first-band filter.
- In the port plane, optical sub-signals are incident on the first-band filter within a predetermined angle range in a backward propagation direction.
Potential applications of this technology:
- Optical communication networks
- Optical signal processing systems
- Optical switching and routing systems
Problems solved by this technology:
- Efficiently separating and manipulating different wavelength bands in optical signals
- Reducing signal loss and crosstalk in wavelength selective switching
Benefits of this technology:
- Improved signal quality and integrity
- Enhanced flexibility and scalability in optical networks
- Higher data transmission rates and capacity
Original Abstract Submitted
The present disclosure relates to a wavelength selective switching apparatus and a related method thereof. The apparatus includes: at least one input port and a plurality of output ports; a dispersion assembly, configured to respectively disperse a received first-band optical signal and a received second-band optical signal into a plurality of first optical sub-signals and a plurality of second optical sub-signals in a dispersion plane; a first-band filter, configured to reflect the plurality of first optical sub-signals and transmit the plurality of second optical sub-signals; and a light redirection device, configured to make each of a plurality of sub-band optical signals to be emitted toward the first-band filter in a redirected manner. In a port plane, a plurality of optical sub-signals are respectively incident to the first-band filter at an incidence angle within a first predetermined angle range in a backward propagation direction.
