Article Abstract

We demonstrate on-chip coherent beam combination of two waveguide amplifiers on Er-doped thin film lithium niobate (Er:TFLN) platform. Our device is built based on an electro-optic modulator fabricated on Er:TFLN. The output power of the coherently combined amplifiers is measured as high as 12.9 mW, surpassing that of previous single waveguide amplifiers based on an Er-doped thin film lithium niobate platform.

Nanoparticles (NPs) doped polymer based optical waveguide amplifiers (OWAs) have been attracting much attention. As an important component of gain medium, the size of NPs has a significant influence on the relative gain of the OWAs. NPs with larger size have improved luminescence properties, but also increase the scattering loss in OWAs.

We demonstrated a monolithic waveguide laser in Er:YAG ceramics fabricated using femtosecond direct laser writing. High-quality Er:YAG ceramics with precisely controlled Er-ion doping were synthesized, providing an optimal medium for laser and amplifier applications. Waveguide structures were inscribed within the ceramics to support low-loss propagation with a large mode area.

High-power spot-ring fiber lasers effectively suppress metal spatter in laser manufacturing such as power battery welding. Increasing expectations regarding processing quality have necessitated the incorporation of additional ring beams to enhance the preheating effect. However, traditional dual-core fiber methods are limited by the waveguide structure.

We propose a novel layerstack for polarization-insensitive (PI) multi quantum well (MQW) semiconductor optical amplifiers (SOAs) using a ternary InGaAs/InGaAs active layer with a tensile-strained barrier. This design achieves PI performance by enhancing TM-mode gain and is compatible with passive waveguides for passive-active co-integration. The SOA exhibits a high gain of 30 dB, broadband operation of 100 nm, and low polarization-dependent gain (PDG), ranging from 1-3.

In this paper, an ultra-wideband distributed feedback (DFB) laser array with matrix grating based on the enhanced self-heating effect is proposed and experimentally demonstrated. 12 lasers are monolithically integrated with a 4 × 3 matrix style with a wavelength spacing of 5 nm. The reconstruction-equivalent-chirp technique is used to simplify the grating fabrication and enhance the precise control of the wavelength spacing.
