Highly-efficient and low return-loss coupling of standard and antiresonant hollow-core fibers

We show results on adopting our new technique, developed for connecting solid-core fibers with hollow-core photonic bandgap fibers, to connect solid-core with antiresonant hollow core fibers. We achieved insertion ...

Angled Interconnection Between Standard Single-mode Fiber and Nested Modeless Antiresonant Fibers

We present angled interconnection between standard single-mode fiber and nested nodeless antiresonant fibers achieving an insertion loss of 0.45 dB and return loss below -60 dB over a wide (1450-1650 nm) spectral range....

Gap design to enable functionalities into nested antiresonant nodeless fiber based systems

By modifying the interconnection design between standard single-mode fiber (SSMF) and nested antiresonant nodeless type hollow-core fiber (NANF), we create an air gap between SSMF and NANF. This air gap enables the insertio...

Functional sample of nested antiresonant nodeless hollow core fibre, type UFE-NANF5-80

Nested antiresonant nodeless hollow core fibre allows transmission of light in transmission spectral bands. Key property is low interaction of light in the hollow core and material of the fibre. Strong response to acoustic signals was achiev...

Coupling Light Into a Hollow-Core Fiber with Mitigated Excitation of Higher-Order Modes

We show experimentally that unwanted crosscoupling into higher-order modes of a hollow-core fiber can be reduced to values close to -40 dB when optimizing the input beam size for their suppression rather than optimizing it for the minimum in...

Gas-Stop Design Towards Low-Loss Connection for Reliable Hollow-Core Fiber Networks

A gas-stop is designed to enable low-loss and hermetic connection between hollow-core fibers. This design enhances robustness of hollow-core fiber networks as it provides efficient connectivity and prevents fiber degradatio...
