TL;DR: The output power level of logic "1" dependence on the operating conditions, such as two input signal powers, injection current, and input signal wavelength, are investigated in detail using the broad-band model of this all-optical half adder.

TL;DR: This work infuses a silica microcapillary-based optofluidic ring resonator with a magnetic fluid, into which pump light is injected by a fiber taper, and results in the first scheme for all-optical tuning of an OFRR, which has great potential in filtering, sensing, and signal processing applications.

TL;DR: In this article, an all-optical tunable microlaser based on the ultrahigh quality (Q)-factor erbium-doped hybrid microbottle cavity is proposed and experimentally demonstrated for the first time.

TL;DR: This work provides a promising solution for on-chip passive nonreciprocal device with the advantages of simple structure, low power consumption and large operating bandwidth.

TL;DR: This work demonstrates a simple and compact scheme to generate ultrawideband (UWB) monocycle pulses utilizing gain saturation of a dark return-to-zero (RZ) signal in a semiconductor optical amplifier (SOA).
