Title: Semiconductor laser
Inventor: UNOSAWA HIROKIYO
IPC: H01S5/00
Filed: 1990-04-06
Abstract: PURPOSE:To improve a vertical radiation angle, and a kink level and to hold easily operable characteristic in practice by asymmetrically disposing band gaps of a p-type clad layer and an n-type clad layer made of AlGaInP crystal. CONSTITUTION:An (AlxGa1-x)0.5In0.5P (0<=x<=0.2) active layer 3 to become a light emitting region is formed in a double hetero structure in which the layer 3 is interposed to be held between two (AlyGa1-y)0.5In0.5P (0.5<=y<=1) clad layers 2 and 4 having larger forbidden band widths than that of the layer 3 and different conductivities on an n-type GaAs substrate inclined from a plan (100) to a plane (011) at an x degrees (0<=X<=16). The same conductivity Ga0.5In0.5P or AlzGa1-zAs (0.4<=z<=1) buffer layer 5 as that of the clad layer is provided, a GaAs layer 6 having reverse conductivity to that of the buffer layer is provided adjacent to the layer 5, and a groove straight to the GaAs layer and the same conductivity GaAs contact layer 8 as that of the adjacent buffer layer is provided. When a band gap difference between the two clad layers 2 and 4 is set to 20meV or higher, its kink level can be improved.

Title: Semiconductor light-receiving element
Inventor: SUSA NOBUHIKO
IPC: H01L31/10
Filed: 1978-07-28
Abstract: PURPOSE: To minimize noise by using a material with a relatively small prohibition band width ΔWg at high resistance in contact with a shot key electrode, using a material with a large ΔWg at low resistance in contact with an ohmic electrode and radiating light from the side of large ΔWg.  
     CONSTITUTION: A high-resistance layer 9 with relatively small ΔWg, such as, In x Ga 1-x As, etc., is provided with a shot key electrode 3, and a low-resistance layer 10 with relatively large ΔWg, such as GaAs, etc., is provided with an ohmic electrode 7 and a light-radiating window 11. A reflection-preventing film 4 and a guard ring 6 are also provided. By employing n-type for semiconductor layers 9 and 10, an ionization rate of a positive hole is assumed to be larger than that of an electron. If a light-radiating energy of ΔWg9<hν<Wg 11  is chosen, a light radiated in the direction of an arrow 8 is made to penetrate through the low-resistance layer 10 and absorbed only by the high-resistance layer 9, and when this element is used as an APD, since an electron does not move due to a barrier qϕB of the shot key joining section and only the positive hole is poured from the layer 9 into a high electric field region of the joining section, noise is lowered.
