We present a Y-branch power splitter design with a multimode section using GaN on Sapphire at telecommunication wavelength. The GaN sample optical properties were also investigated, resulting in a refractive index for the GaN layers nTE=2.289±0.001 and nTM=2.324±0.00. Optimization of the structure parameters for this structure was conducted accurately using BPM methods. The results demonstrated the possibility of realizing a GaN-based Y-branch power splitter for various applications.

Bahasa Abstract

Desain Pembagi Daya Pencabangan Y Rugi-Rugi Rendah Berbasis GaN. Pada penelitian ini dilaporkan desain pembagi daya pencabangan Y dengan memanfaatkan pandu gelombang moda jamak pada panjang gelombang telekomunikasi menggunakan material GaN pada Safir. Hasil pengukuran sifat optik menunjukkan bahwa indek bias sampel GaN pada Safir adalah nTE=2,289±0,001 dan nTM= 2,324±0,00. Dari hasil optimasi parameter struktur dengan metoda BPM ditunjukan bahwa pembagi daya pencabangan Y berbasis bahan GaN.berpotensi untuk direalisasi
