Bragg condition is very sensitive to incident wavelength. With this characteristic, we can diffract wavelength with appropriate Bragg structure. In this letter, we first design an aperiodic structure with the help of simulated anneal algorism

We demonstrate a novel dual-wavelength Nd:YVO4 laser where either or both of its emission lines can be selected and Q-switched electro-optically using a domain-engineered LiNbO3. Electro-optic switching among five wavelengths from the system is obser

We report a fast optical switch in LiNbO3 photonic-circuit chip integrating an electro-optic (EO) polarization-mode converter and a broadband adiabatic polarizing-beam splitter. The device features high EO switching efficiency (~95%) and broadband (>

We report the demonstration of an electro-optic (EO) switchable dual-wavelength (1064- and 1342-nm) Nd:YVO4 laser based on an aperiodically poled lithium niobate (APPLN) chip whose domain structure is designed using aperiodic optical superlattice (AO

We demonstrate an electro-optic (EO) switch or in general, an EO controllable power divider based on a periodically poled lithium niobate (PPLN) polarization mode converter (PMC) and a five-waveguide adiabatic coupler integrated on a Ti:LN photonic c

We demonstrate broadband adiabatic couplers using lithium niobate on insulator (LNOI) waveguides with a footprint reduced by 98% relative to bulk LN devices. LNOI couplers with coupling efficiency >95% across telecom S-C-L bands are obtained.
