1.52um InGaAsP / InP separate confinement quantum well lasers


And 30. 1.52m at the center wavelength (see Figure 2). Fourth, the conclusion we use the LP-MOC ~ D growth of a characteristic wavelength in the two l3m and 1.6um InGaAsP materials, and growth through 36I - I3unlInGaAtnP-Zn prince Yu a separate confinement quantum well laser structure diagram mound f ■ Technology beam) Wn '~ mBihI_I-Figure 2QWLD output spectrum characteristic of a single ● _l (., Chen Songyan other day day: 1.52umInGaAsP/InP quantum well lasers were limited to anchor some of the difficulties of the process of analysis, the system had continuous operation at room temperature InGaAsP separate confinement quantum well lasers References: [1: y ~ mamotoMeta】.

Dr. Meng Xiangwen Professor Li Pu in the room and other support, select an isolated gene with lung cancer as the main project. He has been and improved by using hybrid and 7 Po AP - PCR technology,[link widoczny dla zalogowanych], and achieved some results 7 March this year, he embarked on an advanced 7 mRNA differential display, gene isolation in the application of a highly sensitive fluorescent dyes to replace hazardous great live elements, and using very simple separation and detection devices instead of expensive automatic detection and fluorescence analysis equipment, obtaining encouraging _ 7 between the results of this, he applied 120 pairs of primers with different metastatic potential of two homologous but tumor cell lines to analyze differences in gene expression, separation of more than 20 poor cock table that the gene fragments, of which two gene fragments were cloned and sequence analysis, than vessels, found in highly metastatic cell lines of Anipr973 ~ , is located on human chromosome retroviral LTR and mitochondrial genes, a gene highly expressed, suggesting that these two genes and tumor metastasis.
