Here we present the design and performance of tunable dual-band and wide-angle perfect absorber, consisted of graphene and VO2. Simulation results show the device operating in long-wave infrared region. The two absorption peaks, including location and intensity, can be tuned in a wide range by either electrical, thermal, or their combination.

We demonstrated a femtosecond green laser operating at 532 nm by frequency doubling of a 1 pm linearly-polarized all-fiber-integrated femtosecond chirped pulse amplification system. The 1-pm broad-spectrum seed with a 3 dB spectral bandwidth of 11.3 nm was founded by dispersive wave technology. The average power was scaled up to 6.5 W by two stage ytterbium-doped fiber amplifier and the pulse duration was compressed to 371 fs through grating pair compressor. Finally, a maximum green laser power of 1.25 W was achieved with an input power of 4.7 W by a 5×5×2 mm BBO crystal, corresponding to a conversion efficiency of 26.6 %.

Near-infrared nanophotonics has been massively studied due to its promising ability in addressing the interconnect bottleneck problem [1] and achieving resonator-based sensors with high quality factor [2] [3]. Among the various material platforms that have been applied in near infrared nanophotonics, silicon-on-insulator (SOI) platform offers advantages such as high optical mode confinement, low loss, CMOS compatibility, and mature fabrication [4].

Rare-earth doped semiconductors have attracted continuous attentions for their potential applications in both scientific research and practical fields. It is well-known that the luminescence efficiency of dopant emissions could be highly improved with a wide bandgap host material. As a highly thermally and chemically stable wide bandgap semiconductor, β-Ga2O3 is one of the ideal host materials for lanthanide ions, which could introduce additional energy transitions leading to new luminescence. We have successful grown (2 01) oriented rare-earth (RE) doped β-Ga2O3 (RE: Er, Nd, Pr and Ce) thin films on (000l) Al2O3 substrates using radio frequency magnetron sputtering method. The influences of the dopant contents on the structural, optical, photoluminescence, and photoconductive properties of the thin films have been systematically studied. We found that both the crystal lattice and the photoluminescence of the obtained films depends crucially on the doping level. Moreover, by embedding lanthanide ions, RE:β-Ga2O3 could be a sensitive photoluminescence detecting sensor. This work may provide a prominent candidate for further developing advanced composite materials incorporated with luminescent ions.
稀土掺杂半导体因其在科学研究和实际应用领域的潜在应用前景而不断受到人们的关注。众所周知，采用宽禁带材料可以大大提高掺杂发射的发光效率。作为一种热稳定性和化学稳定性都很高的宽禁带半导体，β-Ga2O3是镧系离子的理想宿主材料之一，它可以引入额外的能量跃迁导致新的发光。我们利用射频磁控溅射方法在(000l) Al2O3衬底上成功地生长出了稀土(RE)掺杂β-Ga2O3 (RE: Er, Nd, Pr和Ce)薄膜。系统地研究了掺杂物含量对薄膜结构、光学、光致发光和光导性能的影响。我们发现，所获得的薄膜的晶格和光致发光都取决于掺杂水平。此外，通过包埋镧系离子，RE:β-Ga2O3可以作为一种灵敏的光致发光检测传感器。这项工作为进一步开发含发光离子的先进复合材料提供了重要的候选材料。

We proposed a tunable planar chiral metamaterial (PCMM) which can achieve a giant and photoexcited tunable circular dichroism (CD) effect. The tunable PCMM is composed of an array of conjugated bilayer wheel structures integrated photoconductive silicon (Si). The conductivity of photoconductive Si pads filled in the gap of wheel structures can be tuned efficiently through illumination with different pump power of infrared light. This results in the modulation of CD effect with modulation depths of 80.6% and 64.3% at 0.93 THz and 1.49 THz, respectively. Due to the tunable CD effect, the proposed PCMM could find many potential applications in integrated terahertz spectroscopic, sensing and imaging devices.

A selectively infiltrated photonic crystal fiber integrated with an embedded directional coupler and a multi-mode interferometer is fabricated by infiltrating three adjacent air holes of the innermost layer with standard 1.48 refractive index liquids. The light propagated between the fiber core and the rods can efficiently be coupled into the satellite waveguides under the phase-matching conditions Furthermore, there is a multi-mode interference produced by fiber core modes and rod high order modes. Such a compact device is demonstrated for high sensitivity simultaneous temperature (∼14.72 nm/°C) and strain (∼13.01 pm/μs) measurement.

We experimentally demonstrate an interesting phenomenon of optical bistability in an integrated optical vortex emitter when injecting high power into the waveguide due to the nonlinear optical effects. We clearly observe a hysteresis loop of the radiation power from the integrated vortex beam emitter when increasing and decreasing the input power.

Monolithic integration of active and passive devices on InP yields a compact circuit with 20 nm tuneability and 30 Gb/s modulation per channel. This results in a chip supporting 180 Gb/s with a high capacity density of 10 Gb/s/mm2.
