• ### Traveling Wave Analysis of Non-Thermal Far-Field Blooming in High-Power Broad-Area Lasers

Publication Year: 2019, Article Sequence Number: 2000207
| | PDF (1675 KB) | HTML

With rising current, the lateral far-field angle of high-power broad-area lasers widens (far-field blooming), which can be partly attributed to non-thermal effects due to carrier-induced refractive index and gain changes that become the dominant mechanism under pulsed operation. To analyze the non-thermal contribution to far-field blooming, we use a traveling wave-based model that properly describ... View full abstract»

• ### Back Surface Plasmonic Grating for Increased Quantum Efficiency of nBn Photodetectors With Ultra-Thin Metamorphic InAs0.8Sb0.2 Absorber

Publication Year: 2019, Article Sequence Number: 7200111
| | PDF (1669 KB) | HTML

Using a 2D metallic grating, we demonstrate the resonant enhancement of the external quantum efficiency of an nBn structure with a 0.5 $\mu \text{m}$ -thick-absorber. A total of two structures were studied with different barrier materials: ternary AlInSb and an InAs/AlInSb superlattice (SL). The device using an SL barrier had ... View full abstract»

• ### High-Resolution All-Optical Imaging of Multimode Profiles in a Saturated Absorption Medium

Publication Year: 2019, Article Sequence Number: 8200106
| | PDF (1996 KB) | HTML

We proposed an all-optical imaging technique based on saturated absorption spectroscopy in an atomic vapor. The atoms are driven by a counter-propagating strong pump laser on a transition which is probed by a comparatively weak probe laser. We show that the different orders of Hermite–Gaussian beam carried by pump laser can be efficiently imaged onto a Gaussian-shaped probe laser within a Rayleigh... View full abstract»
