Frequency Comb Swept Lasers for Optical Coherence Tomography
We demonstrate a frequency comb (FC) swept laser and a frequency comb Fourier domain mode locked (FCFDML) laser for applications in optical coherence tomography (OCT). The fiber-based FC swept lasers operate at a sweep rate of 1kHz and 120kHz, respectively, over a 135nm tuning range centered at 1310nm with average output powers of 50mW. A 25GHz free spectral range frequency comb filter in the c...

متن کاملModulation characteristics of short cavity strained-layer lasers
The low frequency response and damping behavior of four quantum well (4QW) gradedindex separate confinement heterostructure (GRINSCH) and SCH strained-layer lasers are compared. The SCH laser is shown to be better in both respects due to a shorter carrier capture time into the quantum wells. A record 3-dB bandwidth of 28 GHz is reported for a 150 pm cavity length 4QW strained-layer SCH laser. T...
متن کاملElectronic Properties of InGaN/GaN Vertical-cavity Lasers
In vertical-cavity surface-emitting lasers (VCSELs), the optical cavity is formed by mirrors above and below the gain region (Fig. 19.1(a)). The laser light propagates in a vertical direction and typically exhibits a circular beam shape. Internally, the photons pass the gain region in a perpendicular direction , i.e., optical gain is provided over a short propagation distance only and the ampli...
متن کاملOptical properties of photonic crystal heterostructure cavity lasers.
We design, fabricate, and test photonic crystal heterostructure cavity lasers in the InP material system. A heterostructure cavity is formed by interfacing two different photonic crystals such that a dispersion maximum of the inner lattice lies within the band gap of the surrounding lattice. Feedback to slow light modes of the central region results in a lower threshold and single mode operatio...
