Scientific results:

We have theoretically described the physical mechanism responsible for self-injection locking in a semiconductor laser in the case of feedback through a ring fiber resonator. It was experimentally demonstrated the narrowing of the generation line of a standard DFB laser in such a configuration to sub-terahertz values.
On the basis of a DFB laser operating in the frequency self-injection locking mode via a ring fiber resonator we have developed an experimental model of a two-frequency Brillouin laser with a width of each of the lines amounting to less than 1 kHz. It was shown that for the stable operation of the system in the frequency self-locking mode simple active optoelectronic feedback is sufficient. Providing stable resonance in the fiber configuration, such a solution allows to avoid using complex active means of stabilization by combining unique characteristics inherent to lasers with double resonance and a simple design of a fully passive self-adjusting fiber system in one module. The achieved results broaden the understanding of the mechanism of self-injection locking in semiconductor lasers and open new possibilities of controlling their properties.
We have implemented and experimentally tested a phase-sensitive acoustic detector (OTDR) that uses a simple DFB laser, self-stabilized on the effect of frequency self-injection locking as an optical master oscillator. A comparison with a standard commercial device confirmed the efficiency of the proposed system at a length of the sensitive fiber element of over 10 km.
The Laboratory has proposed a scheme for stabilizing harmonic mode locking in a ring fiber laser using acousto-optical frequency shift. We have experimentally demonstrated a configuration of a soliton laser for the telecommunication frequency range (~1550 nm) at a pulse repetition frequency of more than 10 GHz and a level of supermode noise suppression of about 30 dB. Our researchers have developed and experimentally implemented a powerful amplifier based on conical fiber doped with ytterbium.
We have conducted a biomedical research of the effect of low-frequency laser radiation on cancer cell cultures. Our researchers proposed an explanation of the effect of oxidative stress and disruption of the functioning of mitochondria of tumor cells in such interaction.
The Laboratory has proposed a method for amplifying plasmon-polariton waves in the far IR range by drift pumping current when conditions for phase synchronization are implemented.
We have proposed and studied models of a ring fiber laser with an inter-resonator interferometer and mode synchronization by dissipative four-wave mixing.
For the first time we have proposed and experimentally demonstrated a configuration of a pulse laser based on Tm–Ho fiber with adjustable length of the generation wave in the range from 1700 to 1800 nm.
The Laboratory has experimentally demonstrated the narrowband generation (< 300 Hz) of a Brillouin laser based on Er-doped fiber with an array of Bragg gratings.
Our researchers have proposed and investigated a theoretical model of loss compensation, amplification and generation of surface plasmons in single-wall carbon nanotubes.
We have theoretically predicted and researched the generation of Brillouin radiation in microresonators the shift and the intermodale distance of the microresonator. It has been demonstrated that, despite the increasing generation threshold, it is possible to significantly increase the intensity of Brillouin signal compared to the resonance case.
Our researchers have proposed new methods of decreasing supermode noise and precise adjustment of pulse repetition frequency in a fiber laser with harmonic mode locking that use the injection of radiation from an external continuous laser with adjustable wavelength.

Implemented results of research:

The main applied goal of our research that is of commercial interest is the creation of optical generators that have compact dimensions, low costs and unique customer characteristics. The sources developed within the project should be viewed in the context of the development of Russian element base for microwave photonics. Moreover, new sources are in demand for optical communication systems as well as for distributed monitoring and optical gyroscopes.
