Multi-band wavelength dispersive device for use in dense wavelength division multiplexing (DWDM) networks |
摘要 |
Multiplexed grating and grating/prism devices are particularly suited to DWDM optical telecommunications networks, finding utility in optical spectrum analyzers (OSAs) and fiber multiplexer/demultiplexers. The invention may be used to address both single- and dual-band configurations through adjustment of the grating, detector array, and/or inclusion of a fiber-optic switch. As a dual-band OSA covering the C- and L-bands, a device according to the invention may be used to replace two separate OSAs like those currently in production, at only a modest increase in cost relative to a single-band OSA. |
