本文提出了一种光子晶体光纤等离激元折射率生物传感器的理论研究。 提出的光子晶体光纤传感器引入了同时检测线偏振和径向偏振模式的概念,因为基于这两种模式的传感器的感测性能相对较高,这对于选择模式以进行准确检测非常有用。 与这种光子晶体光纤中的任何其他偏振模相比,线性偏振模和径向偏振模的尖锐的单个共振峰对分析物折射率的变化更强且更敏感。 对于线性偏振模式和径向偏振模式,可以获得最大灵敏度,每个折射率单位为10448.5 nm,每个折射率单位为8230.7 nm,以及感度范围为1.33-1.45时的品质因数分别为949.8和791.4。 。 与传统的金金属表面等离子体共振传感器相比,我们的设备更好,可以用作生物传感器。

A scheme for the photonic generation of frequency-tunable millimeter wave and terahertz wave signals based on a highly flat optical frequency comb is proposed and demonstrated experimentally. The frequency comb is generated using two cascaded phase modulators (PMs) and an electro-absorption modulato

We present a simple approach based on photonic reservoir computing (P-RC) for modulation format identification (MFI) in optical fiber communications. Here an optically injected semiconductor laser with self-delay feedback is trained with the representative features from the asynchronous amplitude histograms of modulation signals. Numerical simulations are conducted for three widely used modulation formats (on–off keying, differential phase-shift keying, and quadrature amplitude modulation) for v

A novel scheme of photonic aided vector millimeter-wave (mm-wave) signal generation without a digital-to-analog converter (DAC) is proposed. Based on our scheme, a 20 Gb/s 4-ary quadrature amplitude modulation (4-QAM) mm-wave signal is generated without using a DAC. The experiment results demonstrat

The ultra-compact biosensor based on the two-dimensional (2D) photonic crystal (PhC) microcavity is investigated. The performances of the sensor are analyzed theoretically using the Fabry-Perot (F-P) cavity model and simulated using the finite-difference time-domain (FDTD) method. The simulation res
