Firecomms 665nm VCSELs operate at red wavelengths over 0 to 40°C, and require about one tenth of the operating current of edge emitting lasers. Firecomms multimode red VCSEL is designed for applications where low operating current, excellent beam quality, and visible light are of premium importance.
Firecomms' VCSELs have a bandwidth of up to 3GHz which makes the VCSEL ideal for Gigabit data transmission speeds. Our VCSEL family includes our latest product EDL1000G, a 1x9 POF transceiver module capable of delivering data over POF at rates up to 1.25 Gbps. The transceiver, which is pin compatible with 1x9 optical transceivers for glass fiber, includes Firecomms' OptoLock for quick and easy bare POF terminations without the need for careful fiber cutting or polishing.

Distributed Feedback (DFB) Diode Lasers are fixed wavelength single mode diode lasers. Typical geometrical sizes of the laser chip are 1000µm x 500µm x 200µm (length x width x height). The laser chip is grown by MOVPE of compound semiconductor material. The optical gain is provided by double heterostructure which include several Quantum Wells for electronic confinement. Typcal emitter width range between 3µm and 7µm. The single mode emission is enforced by a Bragg grating with the laser chip. The surfaces of the laser chip act as cavity mirrors due to the difference of the refractive index of the laser material and the surrounding air. The rear facet of the laser chip is provided with a high reflection coating. The front facet of the laser chip is provided with a high quality antireflection coating for avoiding the Fabry Perot modes of the laser chip. Distributed Feedback (DFB) Diode Lasers are available at almost any wavelength between 760nm and 2800nm.

Impressive though the success story of semiconductor lasers has been, there are still several spectral "gaps", wavelengths that cannot be directly accessed with laser diodes. However, nonlinear frequency conversion techniques can be employed to generate tunable laser radiation in the UV, blue and green spectral range. TOPTICA offers state-of-the-art laser systems based on second harmonic generation (SHG), sum frequency generation (SFG) and fourth harmonic generation (FHG).

Distributed feedback (DFB) and distributed Bragg reflector (DBR) laser diodes will greatly ease the life of many scientists. These diodes feature a grating structure within the semiconductor material in order to narrow the emission linewidth. Our DFB and DBR diodes operate in both transverse and longitudinal single mode. Tuning is achieved by modulating either laser current or operating temperature. Single frequency operation is maintained over several hundreds of GHz without mode hops. For maximum frequency stability, we recommend TOPTICA Photonics' patented ColdPack housing. Here, four thermoelectric elements serve to stabilize the laser temperature, or alternatively rapidly heat or cool the diode as appropriate for your particular application.

- Narrow line width (< 5 MHz)
- Frequency tuning via temperature (typ. 25 GHz/K)

Tapered amplifier (TA) diodes combine the "best of both worlds": Laser diodes designed for single mode operation as powerful as broad area emitters for highest output power. Usually, the power of a single mode diode is limited by Catastrophic Optical Mirror Damage (COMD) whilst the higher power of a broad area emitter has the drawback of multiple transverse mode operation. Using a special lateral geometry, where a single mode channel ensures operation at the fundamental transverse mode, while the power density on the output facet is greatly reduced by diffraction of the beam within a subsequent tapered gain section.
- 658 - 1083 nm
- Exceptionally high brightness semiconductor lasers
- Up to 1 W output power
- Nearly diffraction limited beam
- Designed for Master Oscillator Power Amplifier (MOPA) configuration
