  We present the design and anticipated performance of an optically pumped
monolithic all-silicon mid-IR (MIR) Raman laser. For the proposed 3.15 um cw
laser design pumped at a 2.71 um pump wavelength, we estimate a threshold pump
power of < 10 mW and an estimated output laser linewidth of <50 MHz. This
design may pave the road toward demonstration of the first mid-IR silicon Raman
laser.
