A scheme named “spoof” four wave mixing (SFWM) is proposed, where a dynamic refractive index grating induced by the beating of the co-propagating pump and signal is able to modulate a Bragg grating (BG) to create additional reflective peaks (ARPs

A hexangular lattice dual-concentric-core photonic crystal fiber is proposed, which is composed of an inner core to be formed by missing a central air-hole, an outer ring core to be produced by reducing the size of the air-holes of the third ring and

Light-emitting diode (LED) based endoscopic illumination devices have been shown to have several benefits over arclamp systems. LEDs are energy-efficient, small, durable, and inexpensive, however their use in endoscopy has been limited by the difficu

A compact green laser of 1.3 W output at 534.7 nm is generated by intracavity frequency doubling (ICFD) of a 49 edge-emitter laser bar using a MgO-doped (PPLN) bulk crystal. The measured M(2) values of green beam are 12.1 and 2.9 along the slow and f

Intra-cavity frequency doubling of an electrically pumped edge-emitting 980 nm laser diode with PPLN
The growing trend for laser-based projection displays makes intra-cavity frequency doubling (ICFD) of electrically and optically surface emitting diode lasers in the near IR region become more interesting [1–3]. In this letter, we demonstrate for t
