    Abstract: PROBLEM TO BE SOLVED: To form a semiconductor element for radiation reception such that protection against obstacle or error of a signal to be detected is further improved, and production does not need much cost technically. SOLUTION: The semiconductor substrate for radiation reception has a radiation-absorbing active-area 2, and receives electromagnetic radiation within a wavelength range between λ 1 and λ 2 , wherein λ 2 is larger than λ 1 . A filter layer 5 is provided between the active area 2 and a radiation-input coupling face 9. The active area 2 detects electromagnetic radiation having a shorter wavelength than λ 2 . A filter layer 5 absorbs electromagnetic radiation having a shorter wavelength than λ 1 , and transmits electromagnetic radiation having a longer wavelength than λ 1 . COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: A thin-film LED comprising a barrier layer (3), a first mirror layer (2) succeeding the barrier layer (3), a layer stack (5) succeeding the first mirror layer (2), and at least one contact structure (6) succeeding the layer stack (5). The layer stack (5) has at least one active layer (5a) which emits electromagnetic radiation. The contact structure (6) is arranged on a radiation exit area (4) and has a contact area (7). The first mirror layer (2) has, in a region lying opposite the contact area of the contact structure (6), a cutout which is larger than the contact area (7) of the contact structure (6). The efficiency of the thin-film LED is increased as a result.

    Abstract: A semiconductor laser, contains at least one absorbing layer ( 8 ) in its laser resonator, said absorbing layer reducing the transmission T Res of the laser radiation ( 10 ) in the laser resonator for the purpose of decreasing the sensitivity of the semiconductor laser to disturbances created by radiation ( 9 ) fed back into the laser resonator. This reduces fluctuations in the output power due to fed-back radiation ( 9 ).
