| 英文摘要 | Apparatus (10) for interrogating an optical signal (not shown) propagating in an optical waveguide, such as an optical fibre, having an input section (12) and a second section (14) through which light entering from the input section (12) will subsequently propagate. The second section (14) includes a grating portion, such as a tilted chirped fibre Bragg grating (16). The grating (16) causes at least part of the optical signal to be coupled out of the optical fibre, through the fibre cladding. A photodetector (18) is provided generally alongside the grating (16). The photodetector (18) is arranged to collect and detect substantially all of the outcoupled optical signal. The relationship between the optical power outcoupled by the grating (16) and the wavelength of the optical signal is known, allowing a measurement of the outcoupled optical power to be used to determine the wavelength of the optical signal propagating through the grating (16). |
