“…This turns out from the comparable injection efficiencies into a single mode fibre which is in the case of the TL approximately 51%. Similar injection values have been achieved with MOPA-systems [8].…”

“…The TL provides a high output power and a narrow spectral bandwidth combined with a higher stability, yielding a better performance than self-seeded tapered amplifier lasers using a grating for wavelength discrimination. In addition, the TL offers a simplified setup compared to the well-established master-oscillator-power-amplifier (MOPA)-system [8]. Furthermore, we study three ECDL-systems which differ in their implemented medium power laser diode (<100mW), thus leading to different properties, such as wavelength tunability and output power of the lasers.…”

We present and investigate different external cavity diode laser (ECDL) configurations for the manipulation of neutral atoms, wavelength-stabilized by a narrow-band high transmission interference filter. A novel diode laser, providing high output power of more than 1 W, with a linewidth of less than 85 kHz, based on a self-seeded tapered amplifier chip has been developed. Additionally, we compare the optical and spectral properties of two laser systems based on common laser diodes, differing in their coating, as well as one, based on a distributed-feedback (DFB) diode. The linear cavity setup in all these systems combines a robust and compact design with a high wavelength tunability and an improved stability of the optical feedback compared to diode laser setups using diffraction gratings for wavelength discrimination.

“…Obviously, the spontaneous emission rate will be a function of the bias condition, but it also may be altered by the injection of photons from an external source. This effect has been observed in other types of SOAs, and several theoretical explanations exist in the literature 7,8,9,10 . The basic premise behind this phenomenon is that the injected photons increase the photon density inside the cavity.…”

Coherence optimization of vertical-cavity semiconductor optical amplifiers

Vertical cavity semiconductor optical amplifiers (VCSOAs) are attractive devices for use in coherent optical amplification, especially where 2-D amplifier arrays are required. However, the coherence preservation quality of a VCSOA depends strongly on the bias condition, resonant wavelength mismatch, and the optical input power level. We characterize the coherence degree of a VCSOA as a function of these parameters by measuring interference fringe visibility with an interferometer. The dominant factors influencing the contrast of the fringes are the ratio of coherent, stimulated emission photons to amplified spontaneous emission (ASE) photons, and the spectral distortion of the amplified signal. Mostly, the overall gain and the saturation characteristic of the amplifier determine the ratio of stimulated emission to ASE. The spectral distortion of the signal is due to the narrow gain window of the VCSOA, but the effect significantly degrades the visibility only for relatively large wavelength mismatch from the gain peak. Analytic expressions may be used to identify the optimal bias current and optical input power to maximize the amplifier gain and visibility of the interference.

“…After spatial filtering with a single mode fiber, 1% of the power was in a broadband spectral component from spontaneous emission in the tapered amplifier [25]. To quantify the uncertainty in λ zero caused by this broadband component, we characterized the laser spectrum with a grating spectrometer and we accounted for the laser spectrum by modifying Eq.…”
