The strain gradient, the fiber Bragg grating's reflection and the short wavelength loss decide the two stopbands. Because of having no extra loss result from coupler and no high cost result from circuitor, the band pass filter formed by single chirped fiber grating have many good characters such as little insert loss its insert loss is the fiber splice loss, small volume, low cost and excellent property, moreover there is no report about fabricating filter by using this method, thus we will apply national invent paten about the method of fabrication fiber band pass filter using single chirped fiber grating. According to the parameters linearly chirped fiber gratings of Canada BRAGG Photonics Inc.

However, because of the lattice mismatched and imperfect band structure, the application of Si〓Ge〓/Si heterojunction has been constrained. The incorporation of carbon into Si〓Ge〓 layer, provides an additional degree of freedom in Si-based band and strain engineering.

然而，通常外延生长的Si〓Ge〓/Si结构是一种晶格失配异质结，受到临界厚度的限制，而且也不具备理想的能带结构，限制了其进一步的应用。C掺入Si〓Ge〓合金，为Si基能带工程和应变剪裁提供了新的自由度。
