Parallel-coupled wave-guide with symmetrical structure has interesting coupling characteristics and can be used as multiplexer/demultiplexer when certain working requirements are met. The coupling properties in the coupled wave-guide are analyzed theoretically on the basis of two mode interference effect of the propagating waves, wavelength dependence of wave-guide directional coupler is...

ABSTRAK
A micro optical branching circuit [MOBC] array by the use of planar micro lens array and a cubical beam splitter was proposed in a previous study. To study further the performance of the elements of the branching array, the constructed circuit has been implemented by modulating three optical signals on...

Development of optical fiber communication system is mainly due to the progressive influence of optical source. Laser diode as optical source in optical transmission system is of great attention because laser diode produces coherent monochromatic-light. Furthermore, laser diode has a high quantum efficiency, can be modulated at a very high...

ABSTRACT
Recently, there -is a rapidly grow in the field of optical fiber communications, particularly in the technology of fiber waveguide which is used as transmitting media or communication lines. 'Due mayor problem in optical waveguide systems is the coupling loss in connectors or couplers for the purpose of gaining maximum...

The basic principles for the development of laser, an acronym for: light amplification by stimulated emission of radiation, can be traced back to the paper written by Einstein in 1916 when he considered interaction of radiation and matter. In this paper Einstein predicted the existence of stimulated emission and' calculated...

ABSTRAK
A parallel optical switching system using array structure of planar microlens was developed. The optical switching device is much simpler and low costly compared with the electronic one because it is not necessary to convert optical signals to the electronics, execute the interchange and then reconvert back to optics. The...
