    2. OCT swept laser with cavity length compensation

      OCT swept laser with cavity length compensation
      An optical coherence tomography system utilizes an optical swept laser that has cavity length compensator that changes an optical length of the laser cavity for different optical frequencies to increase the length of the laser cavity for lower optical frequencies. Specifically, a spectral separation between longitudinal cavity modes of the laser cavity is shortened or alternatively lengthened as a passband of a cavity tuning element sweeps through a scanband of ...

    3. Long-to-short wavelength swept source

      Long-to-short wavelength swept source
      Most swept external cavity diode lasers tune in the short-to-long wavelength direction (red tuning). Lower relative intensity noise (RIN) and higher output power are typically possible in this direction. We show here that long-to-short tuning (blue tuning) is possible for a short, linear cavity laser that has both low noise and high power. This mode of operation is made possible by nonlinear frequency broadening in the semiconductor optical amplifier (SOA ...

    4. Moody's says Excelitas' proposed $80 million first lien term loan facility to acquire Axsun is a moderate credit negative; ratings unaffected

      Moody's says Excelitas' proposed $80 million first lien term loan facility to acquire Axsun is a moderate credit negative; ratings unaffected
      Moody's Investors Service ("Moody's") says EXC Holdings III Corp.'s (dba Excelitas) proposed $80 million incremental first lien term loan facility to fund the acquisition of Axsun is a modest credit negative, but it does not impact the company's B3 Corporate Family Ratings or stable rating outlook. Following the add-on, the USD denominated first lien term loan will increase to $685 million from $605 million ($681 million ...

    5. OCT system with bonded MEMS tunable mirror VCSEL swept source

      OCT system with bonded MEMS tunable mirror VCSEL swept source
      A microelectromechanical systems (MEMS)-tunable vertical-cavity surface-emitting laser (VCSEL) in which the MEMS mirror is bonded to the active region. This allows for a separate electrostatic cavity that is outside the laser's optical resonant cavity. Moreover, the use of this cavity configuration allows the MEMS mirror to be tuned by pulling the mirror away from the active region. This reduces the risk of snap down. Moreover, since the MEMS ...

    6. Integrated optical coherence analysis system

      Integrated optical coherence analysis system
      Optical coherence tomography (OCT) probe and system designs are disclosed that minimize the effects of mechanical movement and strain to the probe to the OCT analysis. It also concerns optical designs that are robust against noise from the OCT laser source. Also integrated OCT system-probes are included that yield compact and robust electro-opto-mechanical systems along with polarization sensitive OCT systems.

    1. The Mass. court's decision is only one ruling of a much broader case involving 30 trade secret claims against Volcano and subsidiary Axsun Technologies Inc.... today's ruling does not call into question the significant jury verdict from February 2010... the decision does not change the Superior Court of Massachusetts' verdict against Axsun Technologies, ruling that the company must ban the sale of its lasers to Volcano for all fields of use, not just the field of human coronary artery imaging.
