    摘要: Provided are methods of forming an optical coupler. The method includes forming a first waveguide and an in-plane tapered layer on a silicon layer, forming a mask with first and second openings. The first opening is formed between the in-plane tapered layer and the second opening, and the second opening extends from the first opening with a gradually narrowing width. Thereafter, a planar waveguide and a three-dimensional tapered layer are simultaneously formed in the first and second openings, respectively. The planar waveguide has a substantially uniform thickness, and the three-dimensional tapered layer has a thickness gradually increasing with a decrease of the width thereof.

    摘要: Provided are a semiconductor device and a method of forming the same. According to the method, a first buried oxide layer is locally formed in a semiconductor substrate and a core semiconductor pattern of a line form, a pair of anchor-semiconductor patterns and a support-semiconductor pattern are formed by patterning a semiconductor layer on the first buried oxide layer to expose the first buried oxide layer. The pair of anchor-semiconductor patterns contact both ends of the core semiconductor pattern, respectively, and the support-semiconductor pattern contacts one sidewall of the core semiconductor pattern, the first buried oxide layer below the core semiconductor pattern is removed. At this time, a portion of the first buried oxide layer below each of the anchor-semiconductor patterns and a portion of the first buried oxide layer below the support-semiconductor pattern remain. A second buried oxide layer is formed to fill a region where the first buried oxide layer below the core semiconductor pattern.

    摘要: An interband resonant tunneling intersubband transition laser is disclosed, and includes a semiconductor substrate, and a first cladding layer, an active region structure layer and a second cladding layer formed on the semiconductor substrate. The active region structure layer includes quantum well layers and quantum barrier layers that are alternately stacked and have a broken energy bandgap. Thus, the interband resonant tunneling intersubband transition laser operates in a cascade mode in which an intersubband radiative transition and interband tunneling of carriers consecutively and repetitively occur in the active region structure layer, and thus can achieve a high output from a simple, compact structure.

    摘要: Provided is a method of manufacturing a semiconductor device. According to the method, a first buried oxide layer is formed in the semiconductor substrate in a first region, such that a first semiconductor layer is defined on the first buried oxide layer. An active portion is defined by forming a trench in the semiconductor substrate in a second region. A capping semiconductor pattern is formed on a top surface and an upper portion of a sidewall of the active portion. An oxide layer is formed by oxidizing the capping semiconductor pattern and an exposed lower portion of the sidewall of the active portion, such that the oxide layer surrounds a non-oxidized portion of the active portion. The non-oxidized portion of the active portion is a core and one end of the core is connected to a first optical device formed at the first semiconductor.
