DEVICE FOR OPTICAL SPECTRAL ANALYSIS

摘要

The invention relates to a device particularly for application in optical telecommunications, comprising at least one unit (38) with a means (40) for separating an input signal, at least one Bragg grating (44), used in reflection, at least one phase-shifting Bragg grating (46), used in transmission, the separation means being connected to the networks, at least one actuator (52, 54) to tune the wavelength of the networks and at least one means (50) for detection of (a) signal(s) provided by said unit.
