Temporal quadratic solitons and their interaction with dispersive waves in lithium niobate nanowaveguides

“…2(e). More details about this structure can be found in previous work [14,15,22]. Figure 2(d) shows simulated n eff data for FF and SH modes in this waveguide.…”

Parametric resonances and resonant delocalisation in quasi-phase matched photon-pair generation and quantum frequency conversion

“…In a χ 2 -driven SPDC process, a higher energy photon (pump, ω p ) from a bright source is spontaneously converted into a pair of lower energy photons (signal and idler, ω s + ω i = ω p ), see figure 1. In a waveguide, all photons propagate in the same direction and the important parameter which ultimately determines the properties of the generated signal-idler pairs, for example their joint frequency structure, is the momentum (propagation constant) mismatch of the interacting waveguide modes [26]:…”

A Theoretical Study on Rib‐Type Photonic Wires Based on LiNbO3 Thin Film on Insulator

“…The LNOI structure has been pioneered by the groups of Osgood [4] and Günter [5] on smaller substrates. To date, many LNOI PW devices have been demonstrated, such as (CMOS-compatible) electro-optic modulator, [10][11][12][13][14][15][16][17][18][19] (electrooptically tunable) micro-ring or micro-disk resonator, [7,[19][20][21][22][23][24][25][26][27][28][29] LNOI heterogeneous photonic device, [19] grating coupler, [30,31] photonic crystal, [7,[32][33][34] transverse-electric/magnetic (TE/TM)pass polarizer, [35] quantum optics device, [36] as well as some nonlinear devices based on periodically poled LNOI (PPLNOI) PWs. in diameter) LNOI thin-film is commercially available.…”

“…Based on the LNOI thin‐film, researchers have made much effort to develop various ultra‐compact micro‐photonic devices over the past years. To date, many LNOI PW devices have been demonstrated, such as (CMOS‐compatible) electro‐optic modulator, (electro‐optically tunable) micro‐ring or micro‐disk resonator, LNOI heterogeneous photonic device, grating coupler, photonic crystal, transverse‐electric/magnetic (TE/TM)‐pass polarizer, quantum optics device, as well as some nonlinear devices based on periodically poled LNOI (PPLNOI) PWs . These devices are highly efficient, possess great application prospect, and are expected to replace most conventional devices.…”
