“…From these results, an enhancement factor of the coupling constant is estimated to be 13. While the value is slightly smaller than a theoretically predicted value [25,26] F/π ∼ 19 with finesse F = 59 [23], our result surely showed that the coupling strength becomes an order of magnitude larger. This statement holds in comparison to other QFC experiments using PPLN waveguides without cavities in various situations [14][15][16][17][18][19] in which the coupling constant from 0.003 to 0.012 W −1 mm −2 were observed.…”

“…for Ti:LN waveguides We now apply the previous theory to titanium in-diffused lithium niobate (Ti:LN) waveguides in order to study the technological limits of this platform. Ti:LN waveguides have been widely used for classical and quantum applications [5,6,[27][28][29][30][31][32]. They exhibit extremely low propagation losses (<0.1 dB cm −1 ), can guide both TE and TM polarization modes, possess high nonlinearity, allow on-chip manipulation of the light field via integrated beamsplitters and acousto-and electrooptical modulators and can be easily interfaced to fibre network via pigtailing [14].…”

Waveguides in nonlinear materials are a key component for photon pair sources and offer promising solutions to interface quantum memories through frequency conversion. To bring these technologies closer to every-day life, it is still necessary to guarantee a reliable and efficient fabrication of these devices. Therefore, a thorough understanding of the technological limitations of nonlinear waveguiding devices is paramount. In this paper, we study the link between fabrication errors of waveguides in nonlinear crystals and the final performance of such devices. In particular, we first derive a mathematical expression to qualitatively assess the technological limitations of any nonlinear waveguide. We apply this tool to study the impact of fabrication imperfections on the phasematching properties of different quantum processes realized in titanium-diffused lithium niobate waveguides. Finally, we analyse the effect of waveguide imperfections on quantum state generation and manipulation for few selected cases. Studying the impact of fabrication errors on the waveguide widths, we find that the presence of correlated noise plays a major role in the degradation of the phasematching and we suggest different possible strategies to reduce the impact of fabrication imperfections.

“…The reflectance for 1540 nm is about 30 % which is a little bit larger but forms a very lossy cavity. This should give no cavity enhancement effect for the frequency conversion considering its finesse smaller than π [24,25].…”

We show a concept of optical frequency tweezers for tweezing light in the optical frequency domain with a high resolution, which is the frequency version of the optical tweezers for spatial manipulation of microscopic objects. We report the proof-of-principle experiment via frequency conversion inside a cavity only for the converted light. Thanks to the atypical configuration, the experimental result successfully achieves the tweezing operation in the frequency domain, which picks a light at a target frequency from the frequency-multiplexed input light and converts to a different frequency, without touching any other light sitting in different frequency positions and shaking frequency by the pump light.
