In a competitive context, as the physical limits of fibre communication systems become difficult to overcome, in-line 3R regenerators are being considered to improve repeater spacing or system margins. Simultaneously optical routing and switching make their way in optical networks. In this context 3R regenerators are required to insure the expandability of the network. One objective of the ACTS REPEAT project was to ascertain the feasibility of all-optical 3R regeneration and its benefits.","PeriodicalId":322366,"journal":{"name":"Conference Digest. 2000 IEEE 17th International Semiconductor Laser Conference.

The chip has been incorporated into a newly developed, highly efficient module platform. This module utilizes the industry standard 14-pin 'butterfly' format, and has optimized fiber coupling and thermal design. The combination of an excellent chip and an optimized module design has lead to single mode coupled powers in excess of 0.5 W for telecommunication applications that require high reliability.","PeriodicalId":322366,"journal":{"name":"Conference Digest. 2000 IEEE 17th International Semiconductor Laser Conference.

For intersubband lasing scheme an efficient electron extraction from the lowest lasing level is a necessary requirement to achieve the intersubband inverse population, and, hence, lower threshold and higher CW operating temperature. In type-I cascade structures, electron transition into adjacent quantum well, accompanied by LO-phonon emission, is the most effective depopulation mechanism, whereas for type-II design the interband tunneling process is the primary path for electron escape, especially in interband lasing scheme with lower lasing states located in the GaSb layer. In the work we study the interband tunneling depopulation in the intersubband InAs/GaSb/InAs (A/B/A) laser heterostructure.","PeriodicalId":322366,"journal":{"name":"Conference Digest. 2000 IEEE 17th International Semiconductor Laser Conference.
