Mid-infrared trace-gas sensing with a quasi- continuous-wave Peltier-cooled distributed feedback quantum cascade laser
A recently developed distributed feedback quantum cascade laser (QCL) capable of thermoelectric-cooled (TEC) continuous-wave (cw) operation and emitting at ∼ 9 μm is used to perform laser chemical sensing by tunable infrared spectroscopy. A quasi-continuous-wave mode of operation relying on long current pulses (∼ 5 Hz, ∼ 50% duty cycle) is utilized rather than pure cw operation in order to exte...
متن کاملDevelopment of Free Space Optical Link for Broadband Data Communication
To transfer high speed data streams, a line of sight (LOS) broadband free space optical (FSO) communication link has been designed between two private local LANs located at an aerial distance of about 2 km. A laser diode (LD) – avalanche photodiode (APD) combination operating at 1550nm is used to work as an optical trans-receiver system while an Erbium-doped optical amplifier (EDFA) is used to ...
متن کاملFree Space Optical Link Performance Evaluation using AODV and DYMO
Free space optical network gained increasing visibly as a broadband communication network over traditional wireless networks because of their high bandwidth (up to Gbps), low cost easy installation and also license free long range spectrum. Existence of line of site and alignment between the nodes is one of the key requirements for free space optical communication. In this paper the free space ...
متن کاملHigh rate delivery of AirSAR data using an in-flight free space optical communication link
NASA’s AirSAR instrument is a key resource for the remote sensing community. An upgraded data acquisition capability is currently being developed which will enable data collection and storage at rates greater than 1 Gbps. Access to this data has been limited to post-flight analysis. A high data rate free space optical communications experiment is proposed to downlink the AirSAR data during the ...
متن کاملFree-Space Optical Quantum Key Distribution Using Intersatellite Links
Communication schemes employing quantum entanglement open a wide field of possible applications with properties outperforming their classical counterparts. Promising examples are quantum key distribution, quantum dense coding, and quantum state teleportation. We investigate the potential of quantum cryptography, i.e. quantum key distribution (QKD), with special emphasis on the demands and oppor...
