An optical package for mounting VCSEL and PIN diodes for transmitting and receiving optical signals has been developed. The diodes couple to the fibers in a commercial MT connector. The package is quite compact with its physical size significantly smaller than that of the MT connector. This design simplifies the testing and assembly of the optical components because the MT connector with the lo...

In the past twenty years, the quantum properties of matter and light have been applied to the field of information security. Research has advanced to the point that actual devices using quantum properties are transmitting information over considerable distances. At this time, transmission speeds and hardware expense have generally limited the use of quantum devices to distribute keys rather tha...

Radio Frequency Identification (RFID) systems are increasingly being deployed in a variety of applications. In this paper, we propose a light weight mutual authentication protocol which is an improvement over extended LMAP+ protocol. In mutual authentication, the tag and the reader of the RFID systems will authenticate each other before transmitting unique ID of tag. The proposed protocol provi...

Cornea is unique to its transparency. It has Peculiar feature of transmitting almost all the light passing through it. Corneal clarity dwindles with surgical or pathological insults i.e. infections, corneal dystrophies and degenerations [1]. This induced corneal haze impedes the light rays to pass which results in backward scattering of light [2]. Maintaining regular surveillance over resulting...

This study is a quantitative assessment of the luminous energy transmitted through different translucent fiber posts. After embedding the posts in black resin, the blocks were submitted to sequential cuts in a precision machine, and depths of 16 mm, 12 mm, 8 mm, and 4 mm were assessed for light transmission with a digital photometer. The quantitative analysis showed significant differences betw...
