Many uses of lasers place the highest importance on access to specific wavelength bands. For example, mobilizing optical-atomic clocks for a leap in sensing
Thermal noise is the predominant instability in the provision of ultrastable laser frequency by reference to a cavity. Reducing the thermal-noise limit of a

We demonstrate the first heterogeneously integrated high-speed waveguide photodiode (PD) on tantalum pentoxide (Ta2O5, or tantala) for visible light detection
Optical photonic integrated optical clocks on photonic integrated circuits are described. The optical clocks can provide the timing stability of atomic clocks at ultra-low size and power. The optical clocks are be fabricated using CMOS foundry fabrication processes.
A method of designing a continuous-wave laser source having a target output wavelength and an input laser with a wavelength different from the target output wavelength includes the steps of receiving the target output wavelength, and subordinate properties of the laser source; determining a
Apparatus and methods for generating mid-IR frequency combs using intra-pulse DFG. A mode-locked pulse generation laser generates near-IR pulses which are amplified. The amplified pulses are spectrally broadened by a nonlinear element, for example a normal dispersion highly nonlinear fiber (ND-HNLF)
Integrated photonics that enable nonlinear optical processes are important for numerous applications, including precision metrology; microresonator frequency comb generation; optical signal generation and processing; sensing, positioning, and navigation; and generation and manipulation of quantum
An ultrafast electro-optic laser makes a stabilized comb and includes: a comb generator that produces a frequency comb; a dielectric resonant oscillator; a phase modulator in communication with the dielectric resonant oscillator; an intensity modulator in communication with the phase modulator; an
