nanoplus is offering a wide variety of optoelectronic semiconductor emitters specifically designed to satisfy the needs of our customers. Distributed-feedback laser diodes (DFB LDs) at custom specific wavelengths in the range 760 nm to 2.8 µm are one of the main products of nanoplus. DFB LDs show single-mode emission, which means that the emitted optical power is concentrated in a very narrow spectral band (typically static linewidths of less than 5 MHz). A change in the emission wavelength of a DFB LD is achieved by current (or temperature) tuning, so that the DFB emission can be scanned across a targeted molecular absorption line of a specific gas species in tunable diode laser spectroscopy (TDLS).

For applications where no stable single-mode emission is required, nanoplus is offering Fabry-Perot (FP) laser diodes, where the emission is spread out over a spectral band of around 5nm. For applications where coherent light emission is required over a very broad spectral band, superluminescent light emitting diodes (SLDs) with a spectral bandwidth of over 100nm are supplementing the product range of nanoplus. All described devices are of course capable of continuous wave (cw) operation at room-temperature (and above) and are offered in a wide variety of packaging options.

At longer emission wavelengths between 5 and 10 µm, quantum cascade lasers (QCL) are fabricated by nanoplus. LUCENT Technologies has recently licensed various associated patents to nanoplus.
