This paper presents the modeling, design, fabrication, and characterization of ultra-low loss 3D optical waveguides integrated on a glass photonic substrate. A novel, single-step process was developed using moving mask lithography to fabricate a single mode optical waveguide with a built-in turning mirror capable of making 40° or 45° turns for vertical grating couplers or photodetectors, respectively. Planar alignment of the waveguide to fiber interfaces enable passive alignment, contributing to system cost reduction. An optical path with 1.1 dB loss from fiber to die was obtained from optical modeling, while the fabrication of single mode waveguides with built-in mirrors at <1° angular control was demonstrated.

This article presents the modeling, design, fabrication, and characterization of ultra-low loss 3-D optical waveguides integrated on a glass photonic substrate. A novel, single-step process was developed using moving-mask lithography to fabricate a single-mode optical waveguide with a built-in turning mirror capable of achieving 40° or 45° turns for vertical grating couplers or photodetectors, respectively. Planar alignment of the waveguide to fiber interfaces enable passive alignment of the fibers, contributing to system cost reduction. An optical path with 0.81 dB loss from fiber to die was obtained from optical modeling, while the fabrication of single-mode waveguides with built-in total internal reflecting mirrors at <0.2 μm uniformity and <1° angular control was demonstrated.

Proses fabrikasi dan pencirian bagi pandu gelombang optik mod tunggal yang berdasarkan bahan polimer sensitif cahaya, BenzoCyclobutene (BCB 4024–40) dibincangkan. Ketebalan filem polimer bagi pelbagai kelajuan putaran enapan dan indeks biasan polimer diukur menggunakan kaedah prisma gandingan. Pandu gelombang ini difabrikasi menggunakan kaedah fotolitografi dan punaran kimia basah di atas bahan kaca BK7 dan lapisan nipis SiO2 sebagai pelindung. Kehilangan pandu gelombang diukur menggunakan kaedah konvensional ‘cut back’ yang menghasilkan purata kehilangan sebanyak 3.5 dB/cm. Kata kunci: Polimer BenzoCyclobutene; kaedah putaran enapan; kaedah punaran kimia basah; prisma gandingan The fabrication and characterization processes of single mode optical waveguide based on photosensitive BenzoCyclobutene (BCB 4024–40) polymer are described. The polymer film thickness for various coating speed and refractive index are measured by the method of prism coupling. The waveguide is fabricated using the photolithography and chemical etching technique on BK7 glass substrate with a thin layer of SiO2 as cover. The waveguide loss is measured using the conventional cut back method which results on an average loss of 3.5 dB/cm. Key words: BenzoCyclobutene polymer; spin coating technique; chemical etching technique; prism coupling; cutback method
