Abstract

Reported here is the fabrication of tapered silicon core fibers possessing a nano-spike input that facilitates their seamless splicing to conventional single mode fibers. A proof-of-concept 30 µm cladding diameter fiber-based device is demonstrated with nano-spike coupling and propagation losses below 4 dB and 2 dB/cm, respectively. Finite-element-method-based simulations show that the nano-spike coupling losses could be reduced to below 1 dB by decreasing the cladding diameters down to 10 µm. Such efficient and robust integration of the silicon core fibers with standard fiber devices will help to overcome significant barriers for all-fiber nonlinear photonics and optoelectronics.

Fig. 1 Steps of fabrication. (a) Void gap formation in the core of an as-drawn SCF after heat-polishing process. (b) Tapering of the void gap in the core results in a silicon-free region with a CaO/SiO2 core, and a nano-spike. (c) Cleaving of the tapered SCF. (d) Splicing the SCF with a tapered SMF and final cleaving at the other end. (e) An SMF-SCF device with a nano-spike.
Fig. 2
Fig. 2 Optical microscopy images show (a) an as-drawn SCF with a void gap in the silicon core created by heat-polishing, (b) an intermediate index cladding (IIC) layer of CaO/Silica (inside the red circle) around the void core, (c) a nano-spike produced after SCF tapering, (d) the cleaved end facet of the tapered SCF for output coupling, and (e) the splice joint.
Fig. 3
Fig. 3 (a) Simulation of light coupling into a silicon core via the nano-spike encapsulated with an intermediate index (n = 1.6) cladding layer of thickness h = 200 nm and a cladding diameter of 10 µm. Spike coupling loss is 0.35 dB for this geometry. Electric field strength is shown in normalized logarithmic scale (a.u.). (b) Spike coupling loss versus cladding diameter for various IIC layer thicknesses h, and our device which is designated with a star.

(e) Output mode profile after spatial filtering. (f) Loss measurements with a linear fit to the data. Inset shows the cut-back positions. PH = Pinhole, PD = Photodetector.
