“…[14][15][16][17][18] This frequency determines the magnitude of the spectral interval between the comb lines. [19][20][21][22] In the FSF laser, the spectral interval between the comb lines is determined by the delay time in the feedback loop, but not by the modulator operation frequency. 11 It is known that OFCs obtained by various methods have found extremely wide application in science and technology.…”

In this paper we continue to examine various types of optical frequency combs (OFCs) obtained with frequency down-conversion method in a frequency-shifted feedback laser operating in mode-locking regime without an external optical seeding. We propose to apply these combs to solve several problems associated with the feedback loop length and, consequently, time delay variations -for example, distance measurements, determination of the optical materials refractive index value and dispersion. The advantages of OFCs application obtained by the sequential frequency down-conversion method (dual-and quad-combs) in comparison with the initial OFCs, the spectral interval between the lines of which is determined only by the delay time in the feedback circuit, have been demonstrated. The sensitivity of the examined system to the optical path variation in the feedback loop is determined.

“…In recent papers, it has been shown that the acousto-optic tunable filter (AOTF) can be also applied as a device responsible for shifting the frequency of light [ 21 , 22 ]. The AOTF application allows control of all the OFC characteristics by changing the parameters of AO diffraction [ 23 , 24 ].…”

The results of an optoelectronic system—frequency-shifted feedback (FSF) laser experimental examination are presented. The considered FSF laser is seeded only with optical amplifier spontaneous emission (ASE) and operates in the mode-locked regime, whereby the output radiation is sequence of short pulses with a repetition rate determined by the delay time in its optical feedback circuit. In the frequency domain, the spectrum of such a pulse sequence is an optical frequency comb (OFC). These OFCs we call initial. We consider the possibility of tunable acousto-optic (AO) dual and quad-comb frequency spacing downconversion in the FSF laser seeded with ASE and operating in the mode-locked regime. The examined system applies a single frequency shifting loop with single AO tunable filter as the frequency shifter that is fed with several radio frequency signals simultaneously. The initial OFCs with frequency spacing of about 6.5 MHz may be obtained in the wide spectral range and their width, envelope shape and position in the optical spectrum may be tuned. The dual-combs are obtained with a pair of initial OFCs aroused by two various ultrasound waves in the acousto-optic tunable filter (AOTF). The dual-combs frequency spacing is determined by the frequency difference of the signals applied to the AOTF piezoelectric transducer and can be tuned simply. The quad-combs are obtained with three initial OFCs, forming a pair of dual-combs, appearing when three ultrasound frequencies feed the AOTF transducer. The quad-combs frequency spacing is defined by the difference between the frequency spacing of dual-combs. Quad-combs with more than 5000 spectral lines and tunable frequency spacing are observed. The successive frequency downconversion gives the possibility to reduce the OFC frequency spacing form several MHz for initial OFC to tens of kHz for quad-combs. Graphical abstract

“…Usually, it is the electro-optic (EO) modulator, 9,10 or, seldom, an acousto-optic (AO) molulator. [11][12][13][14][15] It was shown 16,17 that the AO tunable filter (AOTF) may be used as the SSB modulator as any AO device shifts the optical radiation frequency due to the Doppler effect. The AOTF application allows to control all OFC spectral characteristics by changing the parameters of AO diffraction.…”
