“…Free Space Optics is now a viable choice for connecting the LAN, WAN, and MAN; and carrying voice, video and data at the speed of light. However, FSO links in the mid-infrared spectrum seemed to be more favorable as lower atmospheric transmission losses increase the reliability of the system, particularly under bad weather conditions with low visibility (Martini et al, 2002).…”

Bridging the so-called "last mile" in communication networks has revived keen interest in free-Space Optics (FSO), also known as fiber-free or fiberless optics, which is a technology that transports data via laser technology. It is a line-of-sight technology that currently enables optical transmission up to 2.5 Gbps of data, voice and video through the air at long distances (4km), allowing optical connectivity without deploying fiber-optic cable or securing spectrum licenses. It is moving closer to being a realistic alternative to laying fiber in access networks. This paper presents an introduction to FSO and the current state of its technology.

“…In free space communications applications [12], [13], [14], [15], the most important difference would be in the rise times of the responses which are, respectively, 50 ps and 81 ps (using the 0%-100% definition of rise time). Although the rising edge in Fig.…”

Abstract-There is a need for a model that accurately describes dynamics of a bound-to-continuum terahertz quantum cascade laser over its full range of operating temperatures and bias conditions. In this paper we propose a compact model which, through the inclusion of thermal and Stark effects, accurately reproduces the light-current characteristics of an exemplar bound-to-continuum terahertz quantum cascade laser. Through this model, we investigate the dynamics of this laser with a view to applications in high-speed free space communications.Index Terms-Free space communication, quantum cascade laser, rate equation, Stark effect, thermal rollover

“…Если систему двойных квантовых ям встроить в волновод квантового каскадного лазера (ККЛ) с распределенной обратной связью и распре-деленными брэгговскими зеркалами, то электрическим полем можно быстро менять эффективный показатель преломления волновода и соответственно частоту излу-чения ККЛ. Это дает возможность на порядок повысить отношение сигнал/шум в системах оптической связи по сравнению с амплитудной модуляцией [3][4][5].…”
