Sistem komunikasi serat optik pada saat ini mempunyai peranan yang sangat penting karena keunggulan-keunggulannya di bandingkan dengan sistem komunikasi yang lain.
Untuk dapat mengetahui kinerja sistem serat optik tersebut maka perlu di ketahui parameter transmisinya antara lain, yaitu rugi rambatan (loss) dan pelebaran pulsa (dispersi).
Dalam tesis ini...

ABSTRACT
The combination of the coupled mode and normal mode theories has been used to formulaic the theoretical performance represented by the coupling length and crosstalk parameters of the X-cut APE-LN SDC fabricated using the benzoic acid as the proton source, where in this case the matrix effective refractive index (MERI)...

The advantages optical fiber in communication field are widely utilized in developing steps from electrical communication to optical communication. Optical fiber communication promise extremely high data rate over long distance transmission without needing to amplify and retransmit along the way. It is well understood that if frequency of the transmitted...

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...

ABSTRACT
The autofluorescence spectra of human tissues excited with 33'7,1-nm line of pulse nitrogen laser have been measured. The autofluorescence spectra of cancerous tissues consistently exhibit characteristic peaks near E530-nm and 690-nm. which do not appear in the spectra of the corresponding normal tissues. Spectroscopic investigation indicates that the porphyrin compounds...

Optical differentiation is one of many methods in the optical data processing that is useful for, e.g. image contouring. In this thesis, the differentiation filter is caried out based on the spatial filtering techniques. The ob ject is transformed with a Fourier lens to obtain the spatial frequency spectrum of...
