摘要： Thermally compensated wavelength division demultiplexers and multiplexers are disclosed. In one aspect, thermally compensated optical systems for use in an optical network are disclosed. The systems include a diffraction grating coupled to a grating mount having a temperature coefficient. The systems further include an optical fiber coupled to a fiber mount having a temperature coefficient and a lens assembly coupled to a lens mount. The lens mount is operable to position the lens assembly between the fiber mount and the grating mount and includes a substantially similar temperature coefficient to the fiber mount.

摘要： A system and method for wavelength division multiplexing and demultiplexing with broadened and flattened passband profiles are disclosed. A spectral modifying element may be used to broaden and flatten the passband profile of associated multiple wavelength optical signals and spectral components. The system preferably includes a light focusing device and a diffraction grating having a direction of dispersion. The spectral modify element primarily transforms or broadens and flattens optical signals in only the direction of dispersion of the associated diffraction grating.

摘要： A system and method for wavelength division multiplexing and demultiplexing are disclosed. The disclosed system may include a fiber optic element operable to transmit a multiplexed light signal. The system may also include a light focusing device, and the fiber optic element may be oriented to project light through the light focusing device. An additional element may be a diffraction grating having a diffraction order greater than one. The diffraction grating may be positioned in a Littrow configuration with respect to the light focusing device and may have a groove spacing equal to or larger than three times the wavelength of light used in the system.
