We show that an Aharonov-Bohm like suppression of optical tunneling can take place in linear and nonlinear twisted multicore optical fiber structures. The energy exchange is analyzed under nonlinear conditions and a viable setting to observe these effects is suggested.

We demonstrate the modulation bandwidth enhancement in integrated coupled DFB lasers. The coupling strength of the dual DFB is tunable duo to a SOA sandwiching in the center. The 3-dB bandwidth is increased from 8.6 GHz to 18.7 GHz under mutual injection locking.

We report a mid-infrared photothermal microscope with sub-micron spatial resolution. Such performance has exceeded the diffraction limit of infrared microscopy and allowed label-free three-dimensional chemical imaging of live cells and organisms. Distributions of endogenous lipid and exogenous drug inside single cells were visualized.

A chaotic interleaving continuous phase modulation (CI-CPM) scheme is proposed for the first time in Visible Light Communication Orthogonal Frequency Division Multiplexing (VLC-OFDM) system to mitigate the problem of Peak-to-Average Power Ratio (PAPR) and overcome the multipath effect from reflections.

We propose a new scheme for ultrasensitive micro-scale ring laser gyroscopes based on the physics of exceptional points. In judiciously de signed non-Hermitian systems, the frequency s plitting becomes proportional to the square root of the gyration speed, thus enhancing the sensitivity to low rotation by orders of magnitudes.

Micro- or nano-lasers are interesting experimental platforms for studying laser physics. They further question our understanding of lasing action, especially in cases where all emission (spontaneous and stimulated) is channeled into very few cavity modes.

The use of a micro-ring resonator (MRR) to enhance the modulation extinction ratio and dispersion tolerance of a directly modulated laser (DML) is experimentally investigated with a bit rate of 25 Gb/s as proposed for the next generation data center communications. The investigated system combines a 11-GHz 1.55-μm directly modulated hybrid III-V/SOI DFB laser realized by bonding III-V materials (InGaAlAs) on a silicon-on-insulator (SOI) wafer and a silicon MRR also fabricated on SOI. Such a transmitter enables error-free transmission (BER< 10−9) at 25 Gb/s data rate over 2.5-km SSMF without dispersion compensation nor forward error correction (FEC). As both laser and MRR are fabricated on the SOI platform, they could be combined into a single device with enhanced performance, thus providing a cost-effective transmitter for short reach applications.
实验研究了采用微环谐振器(MRR)提高直接调制激光器(DML)的调制消光比和色散容，并提出了用于下一代数据中心通信的比特率为25 Gb/s。该系统结合了一个11 ghz 1.55 μm直接调制的III-V/SOI混合DFB激光器，该激光器通过在绝缘体上硅(SOI)晶圆上键合III-V材料(InGaAlAs)和一个同样在SOI上制造的硅MRR实现。这种发射机可以在2.5 km SSMF上以25gb /s的数据速率实现无差错传输(BER< 10−9)，无需色散补偿和前向纠错(FEC)。由于激光和MRR都是在SOI平台上制造的，因此它们可以组合成一个具有增强性能的单一设备，从而为短距离应用提供具有成本效益的发射机。
