Design Constraints of Photonic-Lantern Spatial Multiplexer Based on Laser-Inscribed 3-D Waveguide Technology

Laser-inscribed 3-D waveguide (3DW) technology has been applied to realize photonic-lantern spatial multiplexer (SMUX), which potentially enables lossless mode (de)multiplexing. However, the index contrast Δn between the transparent substrate and the spatially-inscribed waveguides by femto-second la...

Description
Summary:Laser-inscribed 3-D waveguide (3DW) technology has been applied to realize photonic-lantern spatial multiplexer (SMUX), which potentially enables lossless mode (de)multiplexing. However, the index contrast Δn between the transparent substrate and the spatially-inscribed waveguides by femto-second laser pulses is generally smaller than 6 × 10 -3 . It is simulated that a 3DW SMUX with Δn
