High‐coherence visible and near‐visible laser sources are centrally important to the
operation of advanced position/navigation/timing systems as well as classical/quantum …

When a semiconductor laser is subject to optical injection, it can enter the period-one
dynamics through Hopf bifurcation. Under such nonlinear dynamics, equally and oppositely …

Spectrum congestion and demand for higher data rates are driving a push towards higher
carrier frequencies in wireless communications, necessitating sources of exceptionally pure …

Visible, high-coherence optical sources are important to a wide range of applications
spanning spectroscopy to precision timing. Integration of these sources on a semiconductor …

The synthesis of optical frequencies from the primary cesium microwave standard has
traditionally been a difficult problem due to the large disparity in frequency. Recently this …

We present a CMOS-compatible, Q-switched mode-locked integrated laser operating at 1.9
µm with a compact footprint of 23.6× 0.6× 0.78 mm. The Q-switching rate is 720 kHz, the …

We report a method that enables an external‐cavity semiconductor laser to be actively mode
locked at multiples of the radio frequency (rf) drive frequency. The key to this method is the …

A precision and broadband laser frequency swept technique is experimentally
demonstrated. Using synchronous current compensation, a slave diode laser is dynamically …

Optical-frequency synthesizers, which generate frequency-stable light from a single
microwave-frequency reference, are revolutionizing ultrafast science and metrology, but …

We report the development of a high average power, picosecond-pulse, mid-infrared source
based on difference-frequency generation (DFG) of two synchronous master oscillator …
