An optoelectronic component and a method of manufacturing such a component. The component includes at least one pixel comprising a first and a second electrode for electric coupling. An optoelectronically active material is between the electrodes. The optoelectronically active material is a hybrid sol-gel glass that is chemically supplemented with a material affecting the optoelectronic properties. The component is manufactured by spreading the optoelectronically active hybrid sol-gel on the first electrode, hardening the hybrid sol-gel glass by radiation, and forming the second electrode on the optoelectronically active hybrid sol-gel glass.

Optoelectronic component and manufacturing method

The invention relates to a wavelength-tunable laser configuration. The interspace between a laser source (,) and a control element (,), forming an external cavity, is short and has a length of preferably at most a few hundreds of wavelengths of the laser source (,). Also, the control element (,) is electrically tunable, which means that the control element (,) changes the optical properties of the external cavity with a movement of at least one tuning part (,).
