Unlocking Dynamical Diversity 
Optical Feedback Effects on Semiconductor Lasers

Applications of semiconductor lasers with optical feedback systems
are driving rapid developments in theoretical and experimental
research. The very broad wavelength-gain-bandwidth of semiconductor
lasers combined with frequency-filtered, strong optical feedback
create the tunable, single frequency laser systems utilised in
telecommunications, environmental sensing, measurement and control.
Those with weak to moderate optical feedback lead to the chaotic
semiconductor lasers of private communication. This resource
illustrates the diversity of dynamic laser states and the
technological applications thereof, presenting a timely synthesis
of current findings, and providing the roadmap for exploiting their
future potential.

* Provides theory-based explanations underpinned by a vast range of
experimental studies on optical feedback, including conventional,
phase conjugate and frequency- filtered feedback in standard,
commercial and single-stripe semiconductor lasers

* Includes the classic Lang-Kobayashi equation model, through to
more recent theory, with new developments in techniques for solving
delay differential equations and bifurcation analysis

* Explores developments in self-mixing interferometry to produce
sub-nanometre sensitivity in path-length measurements

* Reviews tunable single frequency semiconductor lasers and systems
and their diverse range of applications in sensing and optical
communications

* Emphasises the importance of synchronised chaotic semiconductor
lasers using optical feedback and private communications
systems

Unlocking Dynamical Diversity illustrates all theory using real
world examples gleaned from international cutting-edge research.
Such an approach appeals to industry professionals working in
semiconductor lasers, laser physics and laser applications and is
essential reading for researchers and postgraduates in these
fields.
