Title Effect of silicon oxide coating on a silicon nitride focusing grating coupler efficiency Type (up) Conference Article
Year 2019 Publication EPJ Web Conf. Abbreviated Journal EPJ Web Conf.
Volume 220 Issue Pages 02009
Keywords grating coupler, SiO2
Abstract The dependence of the efficiency of the focusing grating couplers on the period and filling factor before and after deposition of the upper silicon oxide layer was experimentally studied. The obtained data are of practical importance for tunable integrated-optical devices based on silicon nitride platform.

Title Optimization of on-chip photonic delay lines for telecom wavelengths Type (up) Conference Article
Year 2018 Publication J. Phys.: Conf. Ser. Abbreviated Journal J. Phys.: Conf. Ser.
Volume 1124 Issue Pages 051052
Keywords optical delay lines
Abstract In this work, we experimentally studied optical delay lines on silicon nitride platform for telecomm wavelength (1550 nm). We modeled the group delay time and fabricated spiral optical delay lines with different waveguide widths and radii as well as measured their transmission. For the half etched rib waveguides we achieved the losses in the range of 3 dB/cm.

Title Three-dimensional polymer wire bonds on a chip: morphology and functionality Type (up) Journal Article
Year 2020 Publication J. Phys. D: Appl. Phys. Abbreviated Journal J. Phys. D: Appl. Phys.
Volume 53 Issue 35 Pages 355102
Keywords photonic wire bonds, PWB
Abstract Modern microchip-scale transceivers are capable of transmitting data at rates of the order of several terabits per second. In this regard, there is an urgent need to improve the interfaces connecting the chips and extend the bandpass of the interconnections. We use an approach combining silicon nitride nanophotonic circuits with 3D polymer waveguides fabricated by direct laser writing, which can be used as photonic interconnections or photonic wire bonds (PWB). These structures are designed, simulated, fabricated, and optimized for better light transmission at the telecommunication wavelength. An important part of this work is the study of the telecom signal transmission in a 3D polymer waveguide connecting two silicon nitride facing tapers. Two cases are considered: the tapers are one opposite the other or misaligned. Initially, the PWB shape was chosen to be Gaussian and then optimized: the top was circle-shaped and with the lower part still being Gaussian. Transmission losses were measured for both types of waveguides with different shapes. The idea of an optical multi-level crossing for photonic integrated circuits is also suggested as a solution to the problem of interconnections within a single chip.
