A continuously tunable laser monolithically integrated with a semiconductor optical amplifier is reported. The chip is co-packaged with a frequency locker in a 26 pin butterfly module, and features over 40 mW of fibre-coupled power with an SMSR > 37 dB on 34 ITU channels (50 GHz spacing).

A diagnosis of cancer immediately threatens body image. Radiotherapy, chemotherapy and surgery can alter considerably a person's body image. This can have serious effects on the sexuality of cancer patients but these effects, for reasons to be discussed, are frequently dismissed by health professionals. It is argued that if they ignore their patients' sexuality, nurses are failing to deliver holistic care. This paper discusses the key effects of radical treatment on body image and the role nurses may play as counsellors.

Author(s): Burt, Kira | Advisor(s): Hanson, Gail | Abstract: We present a search for a simplified supersymmetric model with pair-produced light supersymmetric bottom quarks decaying to neutralinos. Higgs-type neutralinos (Higgsinos) decay to the Higgs boson and LSP, with at least one Higgs bo son decaying to a diphoton system. Events with at least two $b$-jets and a photon pair in the Higgs-tagged invariant mass window are considered. In $36.2$ $ \textrm{fb}^{-1}$ of proton-proton collision data collected at the CMS experiment at $\sqrt{s} = 13$ TeV, we find no evidence of signal and set lower limits on the production of the bottom squark at a 95\% confidence level at masses of below 350 GeV, with a Higgsino mass of 150 GeV or less.
