The planar waveguide

The planar waveguide

(p.35) 4 The planar waveguide
Quantum Confined Laser Devices

Peter Blood

Oxford University Press

The planar waveguide controls the overlap of the laser mode with the gain material, which drives the stimulated emission process and determines the divergence of the beam on leaving the laser, important for coupling into external elements such as fibres. Through the optical confinement factor and the optical mode width, the waveguide provides the connection between the gain generated by the gain medium (the material gain) and the amplification experienced by the laser mode (the modal gain). Starting with Maxwell’s equations, this chapter provides an introduction to optical modes of transverse electric and transverse magnetic polarisation in a passive, planar waveguide in the weak guiding approximation. The chapter ends with a short introduction to the internal mode loss in a waveguide.

Keywords:   Maxwell’s equations, planar waveguide, optical mode, polarisation, weak guiding, modal gain, material gain, optical confinement factor, optical mode width, internal mode loss
