Bachelor of science in mechanical engineering: The Fine Art Of Nanolasers

Electrical engineering grad pupil Janelle Shane has a knack for photography in addition to communicating nigh science. Also, nanolasers. Blogging at Postcards from the Frontiers of Science, Shane features breathtaking images from her enquiry inward photonics, which inward her ain words means: "I written report light, in addition to the engineering problems you lot tin solve using light."

Shane is utilisation of the Ultrafast in addition to Nanoscale Optics Group led yesteryear electrical engineering professor Shaya Fainman. You powerfulness nation she has a gift for explaining scientific discipline on the nanoscale. To demonstrate how a nanolaser is built, for example, Shane positioned a nanolaser built at UC San Diego side yesteryear side to a hoodoo, which is a skinny tower of stone that protrudes from the  ground.

Shane explains how they are similar:

The ane on the left is a nanolaser, carved yesteryear high-energy plasma in addition to rigid acid, in addition to invisible to the naked eye.  The ane on the correct is a hoodoo, carved yesteryear current of air in addition to rain, in addition to is unopen to twenty ane 1000 one thousand times larger. And nigh sixty ane 1000 one thousand times older.

The argue they await like is that they’re genuinely carved yesteryear like phenomena - dissimilar layers of these pillars are made of materials that are eaten away at dissimilar rates.  In both these cases, the spill out layer’s made out of the hardest material, in addition to is supported yesteryear a pedestal of ever-decreasing thickness.  The hoodoo’s pillar volition eventually endure eaten away, making the pillar topple.  We facial expression upward the same danger when making our nanolasers, where nosotros accept to fourth dimension the etch length carefully to preclude the Light Amplification by Stimulated Emission of Radiation from collapsing.

 Check out Shane's other fun, fascinating in addition to merely patently cool pics on her blog.
