" ABSTRAK
Divais directional coupler dan optical switch merupakan komponen yang dibutuhkan dalam pemrosesan sinyal optik. Kemajuan teknologi wavelength division multiplexing (WDM) dan pertumbuhan lalu lintas internet yang cepat memicu banyak penelitian tentang teknologi switching optik. Galium Nitrida (GaN) merupakan material semikonduktor nitrida kelompok III yang menjadi kandidat menjanjikan untuk divais yang beroperasi pada panjang gelombang komunikasi optik. Pada penelitian ini dilakukan desain directional coupler dan optical switch menggunakan material GaN untuk panjang gelombang telekomunikasi, yaitu 1,55 um. Desain directional coupler terdiri dari pandu gelombang ... "

" ABSTRACT
A good justification for gallium nitride on silicon is a potential for optoelectronic integrated circuits, and its low cost has stimulated the growth of GaN on large size wafers. The application interest for GaN/Si is power electronics. This current work focuses on characterization optical, electro-optical, and microstructural and simulation design of GaN/Si channel waveguide. For the characterization of GaN microstructure, we use SEM, TEM, AFM, and XRD to observe layer thickness, material structure, material roughness, ... "

" Recently, gallium nitride (GaN) material has attracted the attention of researchers as a candidate for third generation semiconductor material for optical telecommunication applications. In this research, a 2x2 multimode interference optical power splitter (MMI) based on a waveguide and ridge structure is proposed using gallium nitride material on a silicon (GaN/Si) substrate for optical telecommunication applications. The design optimization carried out resulted in two optical power splitter designs based on rib (design A) and ridge ... "
