Carefully dispersion- and nonlinearity-managed cascades of gas-filled hollow-core fibers enable, as our theoretical analysis shows, efficient pulse compression with ultrahigh compression ratios. With dispersion and nonlinearity of individual fibers in such cascades optimized toward distinctly different goal functions, millijoule picosecond laser pulses can be compressed to sub-100-GW subcycle field waveforms.

Introduction: Thoracic outlet syndrome (TOS) encompasses multiple symptoms produced by compression of the neurovascular bundle within the thoracic outlet. The subtypes of thoracic outlet are termed for the major affected structure including neurogenic (nTOS), venous (vTOS), and arterial (aTOS) thoracic outlet syndrome. Neurogenic thoracic outlet syndrome accounts for over 95 percent of thoracic outlet syndrome cases and occurs from compression of the brachial plexus.

Significance: Protoporphyrin IX (PpIX) delayed fluorescence (DF) is inversely related to the oxygen present in tissues and has potential as a novel biomarker for surgical guidance and real-time tissue metabolism assessment. Despite the unique promise of this technique, its successful clinical translation is limited by the low intensity emitted.

Aim: We developed a systematic study of ways to increase the PpIX DF signal through acquisition sampling changes, allowing optimized imaging at video rates.

We demonstrate a widely spaced, stabilized, and self-referenced opto-electronic oscillator driven electro-optic modulator based optical frequency comb. Using an ultra-stable Fabry-Perot etalon as a stable reference, we simultaneously stabilize a CW laser and generate a low noise and stable RF oscillation used to drive an electro-optic comb. In such a manner, the Fabry-Perot etalon pins both the carrier-envelope-offset frequency ( ) and the repetition rate of the comb in place ( ), eliminating the need for an external RF oscillator.

Thermal engineering can be used to exploit absorption in a silicon optical cavity. In this work, the steady state profile of the heat generated by absorption is shaped and used to generate a dynamic heterostructure in a weakly confined silicon optical cavity. This is demonstrated in an edge defect photonic crystal optomechanical cavity to produce phonon lasing and sub-GHz optical pulsing with photon-phonon cooperativity of 0.

A coherent optical frequency comb (OFC) with suppressed linewidth is demonstrated based on the spectral broadening of a directly modulated semiconductor microcavity laser with self-injection locking. Due to the high electro-optical response, the directly modulated microcavity laser provides a 10-GHz-spaced seeding OFC with 9 comb teeth in a 10 dB flatness window. Besides, an optical feedback fiber loop with two sub-loops is introduced to reduce the linewidth of the microlaser and suppress the undesired longitudinal modes.
