The adiabatically tapered subwavelength-scale optical fiber tapers (OFTs) have been of interest for many photonic applications. We demonstrate chemical etching-based adiabatic OFTs and their relaxed adiabaticity conditions over broad operation wavelength ranges. The etched OFTs show adiabatically-va...
