| 英文摘要 | Reflective mode coupling refractive index gratings are disclosed. The gratings can couple light of wavelength λi in a fundamental spatial mode of the waveguide (e.g., LP01) to a reflected higher order spatial mode (e.g., LP11), substantially without reflection of any light of wavelength λj ≠ λi in a spectral range Δλ ≲ 0.01 λi. The mode coupling gratings (MCGs) can find a variety of uses in optical waveguide systems. Exemplarily, an MCG can serve as a wavelength-dependent loss element with abrupt (e.g., ∼1 nm) spectral dependence. However, a chirped grating with or without strength modulation can yield an MCG having relatively wide spectral dependence, including variable loss over a relatively wide (e.g., ∼10 nm) spectral range. Both types of MCGs are advantageously used in, for instance, optical waveguide amplifiers. |
