Holographic display has attracted widespread interest because of its ability to show the complete information object and bring people an unprecedented sense presence. The absence ideal recording materials hampered realization their commercial applications. Here we report that response time a bismuth magnesium co-doped lithium niobate (LN:Bi,Mg) crystal is shortened 7.2 ms sensitivity as high 646 cm/J. was used demonstrate real-time holographic with refresh rate 60 Hz, popular high-definition...
The ability to amplify optical signals is of paramount importance in photonic integrated circuits (PICs). Recently, lithium niobate on insulator (LNOI) has attracted increasing interest as an emerging PIC platform. However, the shortage efficient active devices LNOI platform limits development amplification. Here, we report waveguide amplifier based erbium and ytterbium co-doped by using electron beam lithography inductively coupled plasma reactive ion etching process. We have demonstrated...
Integrated optical systems based on lithium niobate insulator (LNOI) have shown great potential in recent years. However, the LNOI platform is facing a shortage of active devices. Considering significant progress made rare-earth-doped lasers and amplifiers, fabrication on-chip ytterbium-doped waveguide amplifiers electron-beam lithography inductively coupled plasma reactive ion etching was investigated. The signal amplification at lower pump power (<1 mW) achieved by fabricated amplifiers. A...
Abstract BiFeO 3 -based materials have attracted considerable attention owing to their room-temperature multiferroic properties and ultrahigh ferroelectric polarization. In this study, La Co co-doped (BLFCO) thin films were fabricated on Pt (111)/Ti/SiO 2 /Si substrate buffered by Nb-doped (0.7 wt.%) SrTiO via pulsed laser deposition. Experiments revealed that the film deposited at 0.2 Pa comprised predominant orientation of (BFO) (111), its surface root-mean-square roughness was 0.96 nm....
In this work, the second harmonic (SH) of higher-order Poincaré sphere (HOPS) beam was introduced and demonstrated with two orthogonal 5%MgO:PPLN crystals. Based on quasi-phase-matching technique, vectorial coupled wave equations were derived to simulate SH HOPS beams through crystals, including cylindrical vector (CVBs), elliptically polarized CVBs (EPCVBs), circularly vortex beams. Then, experimental setup established reveal that EPCVBs present four-lobed structure still exhibit...
