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 investigated in the coupling region. A rough approximation of the dependence is determined based on simplified transfer matrix multiplications followed by more detailed computer calculation ...

Characterizations have been performed on single stage Transversely Excited Nitrogen Laser of Blumlein type. Optical cavity arrangement is varied prior to measurement which shows no significant increase in energy on both configurations of inserting a mirror only and a pair of mirror and a quartz parallel plate. Frequency repetitions respond reveals a small drop in energy at higher frequency i.e. 10 Hz by a factor of 20%. N2 flow rate consideration behaves on the similar ...

ABSTRACT
The molecular weight of Polymer material can be determined using optical system by measuring the intensity of scattered light at low angle light scattering and its the incident beam, based on Rayleigh scattering have developed by Debye has known as Static Light Scattering.
To carry out this measurement, an optical system was constructed using a HeNe laser light with a certain intensity, and the light passed through a polymer solution and its scattered light ...

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 speed, has small size and compact. The application of such optical source is also wide, ranging from optical signal communication to radar optics.
Therefore, laser diode ...

Teknologi sel surya dewasa ini masih didominasi oleh material berbasis silikon, yang mana memiliki keterbatasan dalam perihal tingginya biaya pada proses produksinya. Dye-Sensitized Solar Cells (DSSC) hardir sebagai alternatif dari sel-surya berbasis silikon atas potensi yang dimilikinya dalam perihal performa fotovoltaik yang stabil dan efisiensi dalam segi biaya produksi. Namun, salah satu komponen utamanya, yaitu fotoanoda berbasis material TiO2 memiliki keterbatasan dalam perihal penyerapan spektrum cahaya tampak dari sinar matahari secara efisien dan kehadiran cacat ...
