Invited talk

Multifrequency terahertz (THz) waves with high spectral purity are of pivotal importance to advanced spectroscopy, imaging, and telecommunications. Traditional approaches for producing multifrequency THz waves and THz frequency combs rely on complex setups or sophisticated device structures and are usually limited in bandwidth and efficiency, especially at the spectral range between 0.5 and...

The chemical properties of microcalcifications within the body have been shown to provide a keen insight into the disease state of various cancers.[1] In their invasive form, these microcalcifications exist predominantly as the common calcium phosphate mineral hydroxyapatite. Being a biomineral, these apatites readily incorporate amounts of common biological ions which also have been shown in...

566. Hybrid Mode-Selective Photonic Lanterns for In-Situ Wavefront Sensing and Optimal Injection into Photonic Chips at VLTI

Hybrid mode-selective photonic lanterns (HMS-PLs) are an emerging astrophotonic technology that enable simultaneous mode-selective light injection and wavefront sensing. Unlike conventional photonic lanterns, HMS-PLs selectively couple the fundamental LP01 mode from a multimode input into a dedicated single-mode output, while higher-order modes are distributed among the remaining outputs for...

358. Optimal design of application-specific photonic lanterns using Bayesian optimisation

Contributed Oral

We simulate how modulating the properties of the centre core within a photonic lantern (PL) can greatly affect the mode selectivity of LP modes. Such knowledge can allow for the fabrication of a 2-in-1 monolothic device: a phase-preserving focal-plane wavefront sensor and an optimised science fibre. The novel variation, where a single mode is coupled into a chosen output fibre (and is...

456. Hybrid–Cladding Antiresonant Hollow–Core Fiber for D-Band

In this study, we have fabricated an oval-tube antiresonant HCF with an outer diameter of 4.56 mm × 5.25 mm with different lengths using a 3D printing method for D-band operation. The proposed design employs a non-uniform cladding to shift resonance frequencies and spatially distribute leakage, resulting in lower loss and a broader low-loss transmission window without altering the overall...
