In this paper, we have developed a relatively simple algorithm to calculate the large-signal
dynamic response of DFB lasers by solving the time-dependent coupled wave equations …

A statistical yield analysis is presented for gain-and index-coupled distributed feedback
(DFB) laser structures, allowing a comparison of their single longitudinal mode (SLM) yield …

A computer model called CLADISS is presented for the analysis of multisection diode lasers.
The model allows for the analysis of a wide variety of multisection devices with discrete or …

A novel index-coupled AR-coated DFB-laser diode, which theoretically exhibits a
longitudinally uniform power density is proposed. The proposed structure contains an …

A distributed feedback (DFB) semiconductor laser structure in which pure gain coupling can
be realized is proposed. The fabrication procedure of this structure makes use of a special …

The new paradigm of parity-time symmetry in quantum mechanics has readily been applied
in the field of optics with numerous demonstrations of exotic properties in photonic systems …

We build on former results from our work on parity-time symmetric gratings implemented in
1550 nm distributed-feedback laser diodes to address the design issues raised by the first …

We introduce a semiconductor distributed feedback (DFB) in which the grating is fabricated
out of quantum well (QW) or superlattice multilayers. This approach provides a very simple …

Methods for reducing or eliminating longitudinal spatial hole burning in antireflection-coated,
index-coupled distributed feedback (DFB) lasers are discussed. It is shown that elimination …

A theoretical analysis of distributed feedback (DFB) lasers with mixed gain and index
coupling (partly gain-coupled DFB) is given for perfect antireflection (AR) coatings …
