TLDR
In this article, the authors explore the means by which an adequate return loss can be achieved in a laser package with discrete optics without excessive penalties due to aberrations due to the coupling of reflections to semiconductor lasers.Abstract:
The coupling of reflections to semiconductor lasers can have a catastrophic impact on lightwave system performance at high bit rates. We explore the means by which an adequate return loss can be achieved in a laser package with discrete optics without excessive penalties due to aberrations.read more

Powering the fiber loop optically-a cost analysis
TL;DR: In this paper, the authors investigate the constraints on optical powering in fiber-in-the-loop (FITL) applications and assess its applicability in terms of end-to-end efficiency, loop length, and system cost.

Loss analysis of laser diode to single-mode fiber couplers with glass spheres or silicon plano-convex lenses
H. Karstensen,K. Drogemuller +1 more
TL;DR: In this article, the authors analyzed the single-mode laser diode to singlemode fiber coupling efficiency for couplers with glass ball lenses and silicon plano-convex lenses, respectively.
Journal ArticleDOI
Single-mode fiber packaging for semiconductor optical devices
TL;DR: In this article, a spherical lens is mounted directly on the chip carrier for maximum thermal and mechanical stability and is aligned mechanically rather than actively, while the single-mode fiber alignment is done actively, and the fiber is positioned so as to compensate for misalignments of the ball lens.

Phase perturbation investigation of laser diode for the laser diode to single-mode fiber coupling system
TL;DR: In this article, a phase-perturbation method and an experimental system were established to study the deviation of the laser diode (LD) far-field intensity distribution from the ideal Gaussian.
