I guess the above question (not by me) is answered in the article by now.

Therefore, there is a strong relation between the flowing current and the emitted The highest power conversion efficiency is typically achieved not for the highest output power, but for a somewhat reduced output power, because the required voltage is then lower.Some low-power LDs can emit beams with relatively high The diode driver can also contribute a lot to the laser noise, because even very fast current fluctuations can be transformed into intensity and phase fluctuations of the generated light.When operated under proper conditions, diode lasers can be very reliable during lifetimes of tens of thousands of hours. However, these statements are false or misleading, as: Figure 1: Schematic setup of an edge-emitting low-power laser diode. Here's a picture of a red laser diode, taken from one of several cheap laser modules I have: I am sure they will ultimately be monolithically integrated but this is a tall order given how dissimilar the laser structures are.

modulation found that the refractive index of the active region varies proportionally to carrier density and hence the wavelength varies proportionally to injected current.

As a result, when light propagates through the cleavage plane and transits to free space from within the semiconductor crystal, a fraction of the light energy is absorbed by the surface states where it is converted to heat by In the 1970s, this problem, which is particularly nettlesome for GaAs-based lasers emitting between 0.630 µm and 1 µm wavelengths (less so for InP-based lasers used for long-haul telecommunications which emit between 1.3 µm and 2 µm), was identified. With the advent of BluRay and HD DVDs there is a need for multi-wavelength diode lasers to read/write not only these discs but also red DVD and IR CDs. The result is a large-cross-section single-mode optical beam which is not attainable from in-plane ("edge-emitting") diode lasers. G. P. Agrawal, "Fiber-Optic Communication Systems", Wiley Interscience, Chap.
