Generation of Arbitrary Frequency Chirps with a Fiber-Based Phase Modulator and Self-Injection-Locked Diode Laser [PDF]
, 2006 We present a novel technique for producing pulses of laser light whose frequency is arbitrarily chirped. The output from a diode laser is sent through a fiber-optical delay line containing a fiber-based electro-optical phase modulator. Upon emerging from

International Journal of Cancer, EarlyView.An early first pregnancy is protective against postmenopausal breast cancer. However, pregnancy is also a key contributor to weight gain, and adult weight gain increases postmenopausal breast cancer risk. This prospective cohort study quantified the combined effect of adult weight gain and age at first pregnancy on postmenopausal breast cancer risk ...

Germanium‐Based Mid‐Infrared Integrated Photonics
Laser &Photonics Reviews, EarlyView.The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...
