16 W continuous-wave room temperature front facet output optical power and 74% wallplug efficiency were attained in 100 /spl mu/m-aperture 1.06 /spl mu/m-emitting laser diodes with 2-3 mm cavity length. The lasers are based on AlGaAs/GaAs/InGaAs quantum well asymmetric heterostructures with ...
relaxation. After a brief review of nano-fabrication aspects of dot lasers by self assembled methods as well as by lithography based implantation and etching methods, also laser device properties based on thermodynamics in low dimensional systems will be discussed. Strong emphasis will be put on ...
Then a randomly selected 5 Gbits of the entire generated random bit sequence is fed to the NIST randomness statistical test suite, a well-known benchmark for statistically certifying the randomness of a sequence24. The test suite consists of 16 tests (listed in Fig. 4b, c), and for each ...
In the context of quantum technologies, the generation and manipulation of single photons has become a key element for applications such as quantum communication and quantum computing, as well as quantum metrology, biology and experiments probing the foundations of quantum physics discussed in an accomp...
