Since optical gain was observed from colloidal quantum dots (CQDs), research on CQD
lasing has been focused on the CQDs themselves as gain materials and their coupling with …

We report a colloidal quantum dot (CQD) distributed feedback (DFB) laser structure
containing a chirped grating. The device exhibits single-mode DFB lasing, of which the …

We demonstrate surface emitting distributed feedback (DFB) lasers across the red, green,

Lasers with multi-wavelength colloidal quantum dots (CQDs) can be achieved using
complex grating structures and flexible substrate. The structure contains graduated periods …

Colloidal quantum dots (CQD) are now making their entry to full-color displays, endowed by
their brightness and single-material base. By contrast, many obstacles have been …

By fabricating a submicron-scale grating structure on a bendable polymer substrate, we
