Antimonide Quantum Dots for Mid-Infrared Nano-Photonic Devices

Antimonide Quantum Dots for Mid-Infrared Nano-Photonic Devices

Objective

The 3 - 5 �m window of the mid-IR wavelength range is the window of choice for developing photonic-based products with important societal impact such as photonic sensors for environment monitoring, photonic diagnosis devices for health care, laser assisted surgery, free-space optical communication systems. However, there is actually a lack of suitable laser diodes (LDs) operating in this domain.The main objective of this project is to demonstrate the feasibility of antimonides-based quantum-dots (QDs) nano-photonic quantum-dots laser diodes (QDLDs) operating continuous wave (cw) at room temperature (RT) in the 3-5 �m wavelength range. Sb-based heterostructures, grown on GaSb or InAs substrates, exhibit a number of unique possibilities among III-V compounds in terms of band structure engineering. In particular, it is the only III-V technology exhibiting interband transitions in the mid-IR. However till now no quantum-well laser diode is able to operate cw at RT at wavelengths between 3 and 5 �m. QDs heterostructures are expected to extend the emitted wavelength and to strongly improve the performances of semiconductor LDs (reduced threshold, high operating temperature) as demonstrated with the GaAs and InP technologies. The successful demonstration of Sb-based QDLDs could thus pave the way to the development of high performance mid-IR optoelectronic devices and photonic sensors. However, the properties of Sb-based nanostructures remain unknown up to now. Another goal of our project will be to retrieve a clear picture of their basic physical (structural, electronic and optical (losses and gain)) properties which is a prerequisite to obtaining reliable, high performance, emitting devices. Further, this will allow us to define their field of applications, and in particular to assess the interest of developing other nano-photonic devices. DOMINO will thus open the route to further long-term research on semiconductor nanostructures and nano-photonic devices.
