Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Can you die from obstructive sleep apnoea syndrome (OSAS)?
Studies suggest an independent association between Obstructive Sleep Apnoea Syndrome (OSAS) and cardiovascular death. The purpose of our study is to examine doctors' awareness of this association and to determine whether this correlates with recording of

Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

A case of soft palate schwannoma that developed with obstructive sleep apnea syndrome (OSAS)
Obstructive sleep apnea syndrome (OSAS) caused by tumors in the upper airway is a relatively rare entity. In this report, we present a soft palate schwannoma causing latent OSAS.

Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...

Characterization and Repetition Rate Locking of a 1 GHz Erbium‐Doped ZBLAN Waveguide‐Chip Comb Laser
A compact, erbium‐doped ZBLAN waveguide chip mode‐locked laser that self‐starts, delivers stable ultrashort pulses, and repetition rate locked to a 1 GHz radio‐frequency reference. The laser produces near transform‐limited 324 fs pulses and 12 nm bandwidth with low noise and long‐term stability, with potential applications in optical frequency ...

OSAS : the magnitude of the problem
: Obstructive sleep apnea syndrome (OSAS) is more frequently diagnosed than in the past. Epidemiological studies have confirmed a high prevalence of the disease in middle-aged adults but also in the elderly.
