Tunable lasers are different if we compare with traditional lasers because they can continuously change their emission wavelength, color, in a given spectral range. As such, these quantum devices have found numerous applications in many diverse fields. Tunable lasers have played a crucial and sustained role in advancements of fundamental physics and science. Among basic fields that employ tunable lasers

Concerns about privacy and security have received increased attention with the rapid growth and public acceptance of the Internet, which has been used to create our global economy E. Anonymity has become a necessary and legitimate goal in many applications, Including anonymous browsing on the Web, location-based services (LBS), and electronic voting. In these applications, encryption alone can not maintain the anonymity required by participants. In the past, researchers have developed numerous anonymous communication systems. In general, ....etc

Please let me know the disadvantages of Tor network.
I have few points with me like..
1)Tor network is very slow
2)It require more bandwidth
3)Attacks like Denial of service and Man in middle are possible.
Need more disadvantages..

Thanks in advance :) ....etc

Tunable lasers


Tunable lasers as the name suggests are lasers whose wavelengths can be tuned or varied. They play an important part in optical communication networks. Recent improvements in tunable laser technologies are enabling highly flexible and effective utilization of the massive increases in optical network capacity brought by large-scale application of dense wavelength division multiplexing. Several tunable laser technologies have emerged, each with its own set of tradeoffs with respect to the needs of particu ....etc

Abstract
A tunable micro-electromechanical systems integrated inductor with a large-displacement electro-thermal actuator is discussed here. Based on a transformer configuration, the inductance of a spiral inductor is tuned by controlling the relative position of a magnetically coupled short-circuited loop. Theoretical studies are backed by a variety of fabricated and measured tunable inductors that show a 2 : 1 inductance tuning ratio over a wide frequency range of approximately 25 GHz. In addition, the maximum and minimum quality fa ....etc
