| Title | Ultrafast superconducting single-photon detector with a reduced active area coupled to a tapered lensed single-mode fiber | Type | Journal Article | ||

| Abstract | This paper presents an ultrafast niobium nitride (NbN) superconducting single-photon detector (SSPD) with an active area of 3×3 μm2 that offers better timing performance metrics than the previous SSPD with an active area of 7×7 μm2. The improved SSPD demonstrates a record timing jitter (<25 ps), an ultrashort recovery time (<2 ns), an extremely low dark count rate, and a high detection efficiency in a wide spectral range from visible part to near infrared. The record parameters were obtained due to the development of a new technique providing effective optical coupling between a detector with a reduced active area and a standard single-mode telecommunication fiber. The advantages of the new approach are experimentally confirmed by taking electro-optical measurements. | ||||

| Title | Ultrafast time measurements by time-correlated single photon counting coupled with superconducting single photon detector | Type | Journal Article | ||
| Year | 2016 | Publication | Rev. Sci. Instrum. | Abbreviated Journal |
|

| Keywords | SSPD, SNSPD, TCSPC, jitter | ||||
| Abstract | Time resolution is one of the main characteristics of the single photon detectors besides quantum efficiency and dark count rate. We demonstrate here an ultrafast time-correlated single photon counting (TCSPC) setup consisting of a newly developed single photon counting board SPC-150NX and a superconducting NbN single photon detector with a sensitive area of 7 × 7 μm. The combination delivers a record instrument response function with a full width at half maximum of 17.8 ps and system quantum efficiency ~5% at wavelength of 1560 nm. A calculation of the root mean square value of the timing jitter for channels with counts more than 1% of the peak value yielded about 7.6 ps. The setup has also good timing stability of the detector–TCSPC board. | ||||

| Title | Possibilities of acoustic thermometry for controlling targeted drug delivery | Type | Journal Article | ||
| Year | 2015 | Publication | Acoust. Phys. | Abbreviated Journal |
|
| Volume | 61 | Issue | 4 | Pages | 488-493 |
| Keywords | acoustic thermometry, liposome suspension, thermography | ||||
| Abstract | Model acoustic thermometry experiments were conducted during heating of an aqueous liposome suspension. Heating was done to achieve the liposome phase transition temperature. At the moment of the phase transition, the thermal acoustic signal achieved a maximum and decreased, despite continued heating. During subsequent cooling of the suspension, when lipids again passed through the phase transition point, the thermal acoustic signal again increased, despite a reduction in temperature. This effect is related to an increase in ultrasound absorption by the liposome suspension at the moment of the lipid phase transition. The result shows that acoustic thermography can be used to control targeted delivery of drugs mixed in thermally sensitive liposomes, the integrity of which is violated during heating to the phase transition temperature. | ||||

| Title | The inverse problem of acoustothermography with correlation reception of thermal acoustic radiation | Type | Journal Article | ||
| Year | 2009 | Publication | Acoust. Phys. | Abbreviated Journal |

| Volume | 55 | Issue | 1 | Pages | 114-119 |
| Keywords | acoustic thermography, acoustothermography | ||||
| Abstract | For the one-dimensional inverse problem of acoustothermography with correlation reception of thermal acoustic radiation, an integral equation is presented and experimentally verified. A method of solving the inverse problem is proposed. The method is based on combining the correlation functions of thermal acoustic radiation that were obtained for different distances between the receivers. | ||||

| Title | Photon-number-resolving SSPDs with system detection efficiency over 50% at telecom range | Type | Conference Article | ||

| Keywords | NbN PNR SSPD, SNSPD | ||||
| Abstract | We used technology of making high-efficiency superconducting single-photon detectors as a basis for improvement of photon-number-resolving devices. By adding optical cavity and using an improved NbN superconducting film, we enhanced previously reported system detection efficiency at telecom range for such detectors. Our results show that implementation of optical cavity helps to develop four-section device with quantum efficiency over 50% at 1.55 µm. Performed experimental studies of detecting multi-photon optical pulses showed irregularities over defining multi-photon through single-photon quantum efficiency. | ||||
