ABSTRACT
An experimental micro optical branching circuit (HCBC) array has been constructed by the use of planar microlens. Three substrates of 3x1 nicrolens array have been used as collimating and focusing elements in the proposed circuit. A cube beam splitter was utilized as branching element with a branching ratio 1:1, for...

ABSTRACT
High Voltage measurement based on the electro-optic effect of LiTaOa crystal plate has been developed. This crystal was placed between two parallel plates which more like capacitor arrangement.
On the first step, this system was capable only to measure the do voltage from 0 to 1 kV, and the...

ABSTRAK
Recently, the distributed index microlenses have been introduced as the novel elements for coupling device in microoptic circuitry. A potential advantage of such microlenses as microoptic components is the possibility of gaining a Large nemerical aperture so that incoming Light can be effectively guided, for example in optical coupler, branching...
