在光波波段發(fā)現(xiàn)逆多普勒效應(yīng)

逆多普勒效應(yīng)將推動(dòng)如隱形斗篷等科幻技術(shù)未來(lái)的發(fā)展,逆多普勒效應(yīng)其成為現(xiàn)實(shí)的速度可能會(huì)超過大部門人的想象。
研究職員通過用硅研制出一種人造納米結(jié)構(gòu)的晶體——被稱為“光子晶體”的物質(zhì)來(lái)實(shí)現(xiàn)負(fù)折射率。通過向這個(gè)*的光子晶體“超級(jí)棱鏡”發(fā)射激光束,并且改變“超級(jí)棱鏡”與探測(cè)器間的間隔,成功創(chuàng)造了多普勒效應(yīng)逆轉(zhuǎn)現(xiàn)象。同時(shí),該實(shí)驗(yàn)*得到的光子晶體折射棱鏡,其微米量級(jí)刻蝕深寬比達(dá)到了25:1,這意味著將1億根直徑為頭發(fā)絲三十五分之一、長(zhǎng)度50微米的硅介質(zhì)圓柱整潔排列,刻劃在硅片上。
逆多普勒效應(yīng)zui早由前蘇聯(lián)物理學(xué)家在1968年作出理論預(yù)言,但一直未得到實(shí)驗(yàn)證明。上海理工大學(xué)上海市現(xiàn)代光學(xué)重點(diǎn)實(shí)驗(yàn)室在莊松林院士領(lǐng)導(dǎo)介入下,由陳家璧教授率領(lǐng)的科研組成功逆轉(zhuǎn)了這種在天然前提下無(wú)法發(fā)生的效應(yīng)。
多普勒效應(yīng)是指當(dāng)觀察者和光波源之間存在著相對(duì)移動(dòng)時(shí),光波的頻率會(huì)發(fā)生改變的現(xiàn)象。當(dāng)物體光源和觀察者間隔不斷靠近時(shí),光頻率增高顏色變藍(lán),反之則變紅。而多普勒效應(yīng)逆轉(zhuǎn)則說明當(dāng)光源和觀察者間隔不斷靠近時(shí),光頻率不增高反而降低,光頻率從藍(lán)色波長(zhǎng)減小至紅色波長(zhǎng)。
隱形斗篷這一科幻技術(shù)未來(lái)將可能成為現(xiàn)實(shí),宇宙大爆炸和中宇宙膨脹現(xiàn)象有可能得到顛覆性的解讀。上海理工大學(xué)光學(xué)工程學(xué)科團(tuán)隊(duì)在負(fù)折射光子晶體中觀察到了光波波段逆多普勒頻移的物理現(xiàn)象,并在出版的《天然·光子學(xué)》上刊出該研究成果。這是世界上在光學(xué)領(lǐng)域證明多普勒效應(yīng)的逆轉(zhuǎn),將在天文學(xué)、醫(yī)學(xué)、微電子產(chǎn)業(yè)等方面得到應(yīng)用。
