  1. Micro-Resonator Soliton (3/18/2019) - Nicolas Volet et al. have reported on “Micro-Resonator Soliton Generated Directly with a Diode Laser” in Laser & Photonics Review. An external-cavity diode laser for 1550-nm wavelength is reported with ultra-low noise, high power coupled to a fiber, and fast tunability. These characteristics enable the generation of an optical frequency comb in a silica micro-resonator with […]
  2. Vescent is seeking a Digital Marketing Intern (3/5/2019) - Vescent Photonics, a leading designer of and photonics tools in the Denver, area, is looking for an intern to assist in digital marketing. This is a great opportunity to develop your marketing skills and put them to work. See details here.
  3. Phase Noise Between Two Phase Locked DBR Lasers (12/5/2018) - We measured the phase noise between two phase locked D2-100 DBR Lasers.  The phase noise (integrated from 1 Hz to 100 kHz) was measured to be <1.1 mrad.  Read the complete application note here.
