“…To achieve uniform modification the polarization of the impinging writing beam is oriented parallel to the waveguide writing direction, and the sample is translated along the focal spot at a moderate feed rate of 0.5 mm/s. The details of our fabrication setup may be found in [21]. The birefringence axis of the waveguide is oriented perpendicular to the sample surface.…”

Integrated optical waveguides, manufactured with femtosecond laser writing (FSLW) technology, enable precise control and manipulation of light in complicated photonic chips. However, due to the intrinsically low anisotropy of FSLW waveguides, polarizing integrated devices have had a relatively large footprint. In this Letter, we demonstrate an approach based on stress-induced anisotropy, allowing us to decrease the size of polarizing directional couplers down to 3.7 mm, almost an order of magnitude shorter than previously reported. The measured extinction ratios at the wavelength of 808 nm are 16 dB and 20 dB for the horizontal and vertical polarizations, respectively. We provide a possible theoretical model for the observed effects.

“…The repetition rate of laser pulses creating waveguides was chosen 1 MHz, the pulse length -400 fs, the average radiation power -82 mW. The laser output was frequency doubled to meet optimal focusing conditions with a Mitutoyo Plan APO 100X microscope objective [38]. The two bending zones have a total length of 7.2 mm, which determines the maximum length 4.6 mm of the interaction zone between the cavity and waveguide.…”

Photon modes of reverse rotation in ring QED-cavity coupled with single atom are considered. By applying Schrieffer-Wolf transformation for the off-resonant light-atom interaction, an effective Hamiltonian of the evolution of the photon modes is obtained. Heisenberg equations for the input-output photon mode operators are written and expression for the system wave function is found. The obtained analytical solution shows the condition of the control not quantum gate implementation. Possible on a chip experimental implementation and recommendations for the construction of optical quantum computer using this gate are considered.This work was funded by RFBR according to the research project no. 17-02-00918.

We produced optical waveguides in the 167 Er 3+ : 7 LiYF 4 crystal with diameters ranging from 30 to 100 μm by using the depressed-cladding approach with femtosecond laser. Stationary and coherent spectroscopy was performed on the 809 nm optical transitions between the hyperfine sublevels of 4 I 15/2 and 4 I 9/2 multiplets of 167 Er 3+ ions both inside and outside of waveguides. It was found that the spectra of 167 Er 3+ were slightly broadened and shifted inside the waveguides compared to the bulk crystal spectra. We managed to observe a two-pulse photon echo on this transition and determined phase relaxation times for each waveguide. The experimental results show that the created crystal waveguides doped by rare-earth ions can be used in optical quantum memory and integrated quantum schemes.
