description Device (1) for analysis of optical spectrum of an optical signal, and method for analysis of optical spectrum which exploits said device, wherein the device (1) comprises an optical filter stage (2), having an optical path (5); a photodetector (17) optically connected downstream of the optical filter stage (2); an actuator (18) configured to vary an optical refractive index of at least one section of the optical path (5); wherein the optical filter stage (2) comprises a first Mach-Zehnder interferometer (6) and a first ring resonator (7) connected in cascade to each other to form respective portions of the optical path (5), wherein a difference in respective optical path (dLo) between a first (11) and a second optical branch (12) of the first Mach-Zehnder interferometer (6) is greater than zero, and wherein the first Mach-Zehnder interferometer (6) is optically connected to a remaining portion of the optical path (5) by means of one and only one first port (13) of an input optical coupler (9) and by means of one and only one second port (14) of an output optical coupler (10).
