摘要： Provided is a spectrum detector capable of being miniaturized and which does not require complicated optical axis alignment. The spectrum detector of the present invention comprises: a substrate; a photodetector formed on the substrate and including a semiconductor having a plurality of convex portions; and a wavelength detection circuit for detecting a wavelength of light transmitted through the plurality of convex portions, from light incident on the photodetector. According to the present invention, a small-sized spectrum detector can be provided which can easily detect a peak wavelength distribution included in light of an unknown wavelength, without the use of optical equipment such as a grating or prism, thus dispensing with the need for the optical axis alignment of a complex optical system.

摘要： A light-emitting device operating on a high drive voltage and a small drive current. LEDs (1) are two-dimensionally formed on an insulating substrate (10) of e.g., sapphire monolithically and connected in series to form an LED array. Two such LED arrays are connected to electrodes (32) in inverse parallel. Air-bridge wiring (28) is formed between the LEDs (1) and between the LEDs (1) and electrodes (32). The LED arrays are arranged zigzag to form a plurality of LEDs (1) to produce a high drive voltage and a small drive current. Two LED arrays are connected in inverse parallel, and therefore an AC power supply can be used as the power supply.

摘要： An LED emitting light of wavelength mainly 375 nm or below. The LED includes a GaN layer (16), an n-clad layer (20), an AlInGaN buffer layer (22), a light emitting layer (24), a p-clad layer (26), a p-electrode (30), and an n-electrode (32) arranged on a substrate (10). The light emitting layer (24) has a multi-layer quantum well structure (MQW) in which an InGaN well layer and an AlInGaN barrier layer are superimposed. The quantum well structure increases the effective band gap of the InGaN well layer and reduces the light emitting wavelength. Moreover, by using the AlInGaN buffer layer (22) as the underlying layer of the light emitting layer (24), it is possible to effectively inject electrons into the light emitting layer (24), thereby increasing the light emitting efficiency.
