TL;DR: In this article, an all-optical UWB pulses generation and modulation scheme based on a semiconductor optical amplifier and a DWDM is proposed and demonstrated, which has potential applications in multiuser UWB-over-fiber communications systems.

TL;DR: In this paper , the authors theoretically demonstrate the existence of symmetry-broken polaritons, with hyperbolic dispersion, in a high-symmetry crystal, and demonstrate that an optical disk-antenna positioned on the crystal surface can act as an in-plane polarized excitation source, enabling dynamic tailoring of the asymmetry of hyper-bolic polariton propagation in the high symmetry crystal over a broad frequency range.

TL;DR: In this paper, a polarization rotator that converts the input TE 1 mode to TM 1 mode is proposed and demonstrated theoretically, with the conversion efficiency higher than 90% over the C-band, with excess loss as low as 0.35dB.

TL;DR: In this paper , a phase-coded linearly frequency modulated (LFM) signal generator was proposed for multi-purpose radars, whose center frequency and bandwidth can be both adjusted by changing the wavelength of the tunable laser source and the peak-to-peak voltage of the driving signal.

TL;DR: In this article, a photonic multiple microwave frequency measurement system is presented based on a swept frequency silicon microring resonator, which has a measurement bandwidth, accuracy and multi-frequency resolution of 25 GHz, ±510 MHz and 5 GHz, respectively.
