An underwater propulsion device is disclosed comprising two sleeves for fitting around each of a user's lower legs, with each sleeve mounting a propulsion unit, and the sleeves being connectable by a bar between them during underwater operation of the device by the user.

Underwater propulsion device

A heterostructure with reduced optical losses is disclosed. The heterostructure includes a set of n-type layers; an active region that generates radiation at a peak emitted wavelength; and a set of p-type layers located adjacent to the active region. A reflective structure can be located adjacent to the set of p-type layers. A thickness of the set of p-type layers can be configured to promote constructive interference of the reflected radiation with radiation emitted by the active region in a direction toward the set of n-type layers.

Optoelectronic device with reduced optical loss

A solution for fabricating a semiconductor structure is provided. The semiconductor structure includes a plurality of semiconductor layers grown over a substrate using a set of epitaxial growth periods. During each epitaxial growth period, a first semiconductor layer having one of: a tensile stress or a compressive stress is grown followed by growth of a second semiconductor layer having the other of: the tensile stress or the compressive stress directly on the first semiconductor layer.
